Dear Mr. Spirgel,

We  would  like to  acknowledge  the  receipt  of the  Securities  and  Exchange
Commission's  (the "SEC" or "Staff") comments dated 18 November 2004 on our Form
20-F for the fiscal year ended 31 March 2004. We will be addressing the comments
in future filings as suggested in the Staff's comment letter. Our next filing of
our Form 20-F with the SEC will be the filing for the fiscal year ended 31 March
2005,  which is expected to be filed with the Staff in early June 2005.  In this
letter we are providing  supplemental  information for those comments  (comments
no. 1, 2, and 3) that require further explanation.

The headings and page numbers below  correspond to the headings set forth in the
comment letter of 18 November 2004. The Staff's comments are highlighted in bold
below  followed  by BT Group plc's (the  "company",  the  "group"  and/or  "BT")
responses.

Comment 1- (k) deferred taxation, page 127.

We note your disclosure under note (k) that previously  recognized  deferred tax
liabilities  were released in the 2003  financial year as a result of changes in
circumstances.  Supplementally tell us the nature of the circumstances and their
related impact on your presentation of net income under US GAAP. Cite your basis
in the accounting literature.

        Response 1.

        As noted in footnote 7 to our financial statements, "Profit on sale of 
        fixed assets investments and group undertakings", in the year ended 31 
        March 2002 we sold our effective interest in Japan Telecom Co. Limited 
        and its interest in J-Phone Communications Co. Limited and our interest 
        in Airtel Movil SA which gave rise to realised profits on the disposals 
        of GBP2,538 million and GBP844 million, respectively.

        Both investments were held through Dutch holding companies and the 
        resulting profits from these disposals were covered by a Dutch tax 
        exemption, meaning that the capital gains on these disposals were exempt
        from taxes in Holland but were still exposed to taxes in the United 
        Kingdom should the Dutch holding company distribute the gains generated 
        on the sale of the investments either through a distribution or a 
        capital transaction to BT Group.  At 31 March 2002, there was no 
        intention to repatriate the gains from the Dutch holding company and 
        thus under UK GAAP no deferred tax liability was recorded.  For US GAAP 
        purposes, a deferred tax liability of approximately GBP979 million was 
        recorded in relation to the temporary difference between the book basis 
        of the investment in the Dutch holding company (which was at historical 
        cost) and the tax basis of the investment (which included the capital 
        gains generated upon disposal) as it was determined that the proceeds 
        (including the gain) would eventually either be transferred back to BT 
        Group or reinvested in other qualifying assets.  In either scenario US
        GAAP would require a deferred tax liability to be booked in relation to 
        the capital gain.

        In July 2002, after the date on which the 2002 Annual Report and Form 
        20-F was approved and filed, the Finance Act in the United Kingdom was 
        enacted. This introduced new legislation with effect from 1 April 2002 
        which brought in a "substantial shareholding exemption", under which 
        certain qualifying gains would not be taxable in the United Kingdom. 
        Based on the new legislation, the repatriation of gains on the disposals
        were expected to be permanently sheltered from UK tax. 

        Accordingly as at 31 March 2003, there was no longer a temporary 
        difference between the book and tax values of the Dutch holding company 
        and as such there was no longer a need to carry a deferred tax liability
        in relation to the capital gains incurred in conjunction with the 
        disposal of the investments described above for US GAAP purposes.  
        Accordingly, under US GAAP,  the GBP979 million deferred tax liability 
        was released through the profit and loss account during the year ended 
        31 March 2003 in accordance with the guidance set forth in paragraph 27 
        of SFAS No. 109, "Accounting for Income Taxes", which states that 
        "deferred tax liabilities and assets shall be adjusted for the effect of
        a change in tax laws or rates. The effect shall be included in income 
        from continuing operations for the period that includes the enactment 
        date."

        Comment 2 - (k) deferred taxation, page 127.

        We further note your disclosure of deferred tax assets and liabilities 
        at March 31, 2004.  Supplementally provide, and in future filings 
        include, more details of the differences between deferred taxation under
        UK GAAP versus US GAAP.  Also, revise to include the disclosures 
        required by SFAS 109 to comply with Item 18 of Form 20-F.

        Response 2.

        We have re-examined our disclosure of deferred tax assets and 
        liabilities at 31 March 2004 included in footnote 12, "Tax on profit 
        (loss) on ordinary activities", footnote 27, "Provisions for liabilities
        and charges", and note (k), "Deferred taxation" to footnote i, 
        "Differences between United Kingdom and United States generally accepted
        accounting principles" in United States Generally Accepted Accounting 
        Principles.

        The following is a reconciliation from UK GAAP to US GAAP of both our 
        deferred tax asset and liability accounts as at 31 March 2004:

        As disclosed in footnote 12 to our financial statements, the group had 
        overseas corporate tax losses of approximately GBP1 billion and 
        unutilised capital losses estimated to be in excess of GBP10 billion 
        that have not been recognised as deferred tax assets under UK GAAP.  
        These losses generate a deferred tax asset under US GAAP, however, there
        is a full valuation allowance reserved against this asset as we have 
        determined it is not more likely than not these assets will be realised 
        in the future.

        In addition, we have reviewed the disclosure requirements of SFAS 109 as
        noted in paragraphs no. 43 - 48 of the standard.  In future filings we 
        will include additional details within our US GAAP footnote regarding 
        any valuation allowances booked against deferred tax assets and their 
        movement from period to period.  We will also disclose the amounts and 
        expiration dates of tax credit carryforwards for tax purposes.

        Comment 3.

        Supplementally provide us with your evaluation of FIN 46 (R) for your 
        investment in Albacom SpA.

        Response 3.

        FIN 46(R) "Consolidation of Variable Interest Entities" requires 
        companies to determine whether they hold interests in a variable 
        interest entity ("VIE") and, if so, to consolidate any VIEs for which 
        they are the primary beneficiary.

        The following is the evaluation of FIN 46 (R) for our investment in 
        Albacom SpA ("Albacom") as at 31 March 2004.

        Key facts regarding the investment and capital structure of Albacom

1.      As at 31 March 2004, BT held 26% of the equity capital of Albacom via a
        100% owned intermediate holding company, Albacom Holdings Ltd ("AHL"). 
        Albacom is a fixed network telecoms supplier in Italy and has a large 
        fibre optic network. Albacom deals mainly with business customers. The 
        total book value of the share capital of Albacom as at 31 March 2004 was
        EUR50.7 million, consisting of 50.7 million ordinary shares with a 
        nominal value of EUR1 each.

2.      The other shareholders in Albacom (including their industry sectors and 
        their respective equity interests) are as follows:



        
        Name of shareholder                                   Industry                       Equity interest
                                                                                       
        
        BT                                                    Communications                      26.0%
        
        Ente Nazionale Idrocarburi SpA (ENI)                  Oil & gas                           35.0%

        Banca Nazionale del Lavoro SpA (BNL)                  Commerical banking                  19.5%

        Mediaset SpA                                          Media                               19.5%


        In addition to the contributed share capital each of the 
        shareholders have also made shareholder loans to Albacom.  The
        respective balances of these loans for each shareholder at 31 March 2004
        are as follows:




           Name of shareholder                                       Percentage of total
                                                    Amount             shareholder loans
                                                   EUR'000
                                                               

           BT                                       33,165                           30%
           ENI                                      23,089                           22%
           BNL                                      24,873                           24%
           Mediaset SpA                             24,873                           24%
           Total                                   106,000                          100%



        These loans are repayable in 12 months and rank sub-ordinate to the 
        bank loan referred to below. Interest is payable at 12 months Euribor 
        plus 0.85%. This rate was negotiated at arms length between the 
        shareholders,.

        The BT, BNL, and Mediaset balances are marginally higher than their 
        respective equity interests because ENI did not fully participate in the
        most recent tranche of shareholder funding.

3.      In addition to the shareholder loans described above, Albacom has 
        entered into a  EUR250m bank loan on normal commercial terms from BNL 
        (one of the shareholders) on which interest is payable.  This loan has 
        been guaranteed by the other shareholders and is senior to the 
        shareholder loans. The extent of the guarantee is in proportion to each 
        investor's shareholding. However, BT has agreed with the other 
        shareholders, including BNL, that the maximum amount of its exposure 
        under this guarantee is capped at approximately EUR35 million.

4.      The Albacom board of directors comprises 11 directors, and BT appoints 3
        members to the board, which is in proportion to its equity shareholding.
        BT does not participate in the day to day management of Albacom.

5.      BT transacts with Albacom as a supplier of telecommunication services 
        on normal arms length commercial terms and the level of trading is not 
        material to either BT or Albacom (Year ended 31 March 2004: Total 
        Albacom revenue - EUR638m, Revenue from BT - EUR32 million). Albacom 
        also trades with its other shareholders (Year ended 31 March 2004: 
        Revenue from BNL - EUR48m, Revenue from ENI - EUR105m, Revenue from 
        MediaSet - EUR21m)

6.      BT accounts for Albacom as a joint venture (equity investee) and 
        recognises its share (26%) of the periodic gains and losses of Albacom.

7.      Under the terms of the shareholder agreements, each of the shareholders 
        has pre-emption rights (i.e. right of first refusal) should one 
        shareholder wish to divest their holding. However, based on our review 
        of these agreements, we do not believe that any of the parties is 
        related, or that there are any de facto principal or agency 
        relationships between the investing parties (as specified in paragraph 
        16 of FIN 46(R).

        Application of US GAAP

        Scope of FIN 46(R)

        To determine whether Albacom is within the scope of FIN 46(R), paragraph
        4(h) must first be analysed:

        4h.       An entity that is deemed to be a business under the definition
        in Appendix C need not be evaluated by a reporting enterprise to 
        determine if the entity is a variable interest entity under the 
        requirements of this Interpretation unless one or more of the following 
        conditions exist (however, for entities that are excluded by this 
        provision of this Interpretation, other generally accepted accounting 
        principles should be applied):

               (1) The reporting enterprise, its related parties, or both 
               participated significantly in the design or redesign of the 
               entity. However, this condition does not apply if the entity is 
               an operating joint venture under joint control of the reporting 
               enterprise and one or more independent parties or a franchisee.

               (2) The entity is designed so that substantially all of its 
               activities either involve or are conducted on behalf of the
               reporting enterprise and its related parties.

               (3) The reporting enterprise and its related parties provide more
               than half of the total of the equity, subordinated debt, and 
               other forms of subordinated financial support to the entity based
               on an analysis of the fair values of the interests in the entity.

               (4) The activities of the entity are primarily related to 
               securitizations or other forms of asset-backed financings or
               single-lessee leasing arrangements.
 
        Although, Albacom is a properly constituted trading entity with inputs, 
        processes, revenues, fixed assets and employees, the investment that BT 
        holds in the entity is held through an intermediate holding company 
        (AHL), which was set up by  BT. As a result we believe the business 
        exemption of appendix C to FIN 46(R) does not apply with regard to 
        Albacom.

        Determination of variable interest entity

        As such, a FIN 46(R) paragraph 5 scoping analysis must be performed. The
        italicised text that follows is taken from FIN 46(R)

            5. An entity shall be subject to consolidation according to the 
        provisions of this Interpretation if, by design, the conditions in a, b 
        or c exist:

            a.    The total equity investment at risk is not sufficient to 
        permit the entity to finance its activities without additional 
        subordinated financial support provided by any parties.

        All of Albacom's debt is provided by the four shareholders. There is no 
        subordinated financial support from non- shareholders. Although the bank
        loan is under normal commercial terms from BNL, it is from a one of the 
        shareholders, with the remainder guaranteed by the other shareholders. 
        Albacom has made losses to date, but management expected the entity to 
        be profitable in the future. Losses thus far have been absorbed by the 
        shareholders in direct proportion to their equity holdings.

        Upon examination of Albacom's capital structure and given the fact that 
        all of Albacom's debt is provided by, or guaranteed by, the four equity 
        investors we believe it is reasonable to assume that the equity invested
        is insufficient to finance Albacom's activities.  Since the equity is 
        not sufficient, Albacom should be treated as a VIE per the guidance in 
        FIN 46(R).

            b.    As a group the holders of the equity investment at risk lack 
        any one of the following three characteristics of a controlling 
        financial interest:

            1. The direct or indirect ability through voting rights or similar 
            rights to make decisions about an entity's activities that have a 
            significant effect on the success of the entity. The investors do 
            not have that ability through voting rights or similar rights if no 
            owners hold voting rights or similar rights (such as those of a 
            common shareholder in a corporation or a general partner in a 
            partnership).

        As a group, the shareholders have the ability to make decisions about 
        the activities of Albacom, along with their representation on the Board 
        of Directors, which is in proportion to their respective shareholdings.

           2. The obligation to absorb the expected losses of the entity.  The 
           investor or investors do not have that obligation if they are 
           directly or indirectly protected from the expected losses or are 
           guaranteed a return by the entity itself or by other parties involved
           with the entity.

        As a group, the shareholders have the obligation to absorb losses of the
        entity and have done so in proportion to their respective shareholdings.

             3. The right to receive the expected residual returns of the 
             entity.  The investors do not have that right if their return is 
             capped by the entity's governing documents or arrangements with 
             other variable interest holders or with the entity.

        As a group, the shareholders of the equity investment at risk do have 
        the right to receive the expected residual returns of the entity.

            c. The equity investors as a group also are considered to lack 
        characteristic (b)(1) if (i) the voting rights of some investors are
        not proportional to their obligations to absorb the expected losses 
        of the entity, their rights to receive the expected residual returns
        of the entity, or both and (ii) substantially all of the entity's 
        activities (for example, providing financing or buying assets) 
        either involve or are conducted on behalf of an investor that has 
        disproportionately few voting rights.  For purposes of applying this
        requirement, enterprises shall consider each party's obligations to 
        absorb expected losses and rights to receive expected residual 
        returns related to all of that party's interests in the entity and 
        not only to its equity investment at risk.

        The voting rights of all investors are proportional to their obligations
        to absorb the expected losses of the entity and to receive the expected 
        residual returns of the entity

     Determination of primary beneficiary

        Having established that Albacom is a VIE, based on the analysis of 
        paragraph 5a, BT needs to determine whether it is required to 
        consolidate Albacom as the primary beneficiary in this VIE, in 
        accordance with paragraphs 14 and 15.

             14. An enterprise shall consolidate a variable interest entity if 
        that enterprise has a variable interest (or combination of variable 
        interests) that will absorb a majority of the entity's expected losses, 
        receive a majority of the entity's expected residual returns, or both. 
        An enterprise shall consider the rights and obligations conveyed by its 
        variable interests and the relationship of its variable interests with 
        variable interests held by other parties to determine whether its 
        variable interests will absorb a majority of a variable interest 
        entity's expected losses, receive a majority of the entity's expected
        residual returns, or both. If one enterprise will absorb a majority of a
        variable interest entity's expected losses and another enterprise will 
        receive a majority of that entity's expected residual returns, the 
        enterprise absorbing a majority of the losses shall consolidate the 
        variable interest entity.
        15. The enterprise that consolidates a variable interest entity is 
        called the primary beneficiary of that entity...

       Based on the quantitative and qualitative analysis set out below, BT is 
       satisfied that it is not the primary beneficiary in Albacom.

        The primary beneficiary is the reporting enterprise that is obligated to
        absorb the majority of the VIE's expected losses. Losses to date have 
        been absorbed in direct proportion to the shareholders' equity holdings.
        At such point that equity is extinguished, losses would be absorbed by 
        shareholder loans and then by bank debt. BT does not hold a majority of 
        any of these instruments and losses would be absorbed rateably by 
        parties in accordance with each shareholders respective holding 
        percentage. Accordingly, in no circumstance would BT expect to absorb a 
        majority of the expected losses of Albacom. BT also considered the 
        trading between Albacom and BT and determined that these arms length 
        transactions were not material in the determination of the primary 
        beneficiary.

        (Note: For the purpose of evaluating the extent of each shareholder's 
        exposure to losses at Albacom, we used the book values of each 
        shareholder's interests in the table above because this is an objective 
        measure, and the relative significance of each shareholder's interest 
        would not change if fair values were used instead of book values.)
 
        Conclusion
        As set out above, Albacom appears to be a VIE because it meets the 
        criteria specified  in paragraph 5a of FIN 46(R).  However, given BT's 
        level of voting interest, the lack of a de facto relationship with other
        investors and the quantitative and qualitative analysis performed, BT 
        does not believe that it is the primary beneficiary of the VIE and 
        accordingly, is  not required to consolidate Albacom. Instead, Albacom 
        is treated as a joint venture accounted for under the equity method.

        On 3 December 2004, BT announced that it will take 100% control of 
        Albacom, following acceptance of BT's offer to the other shareholders to
        purchase their holdings. This transaction was negotiated on an arms 
        length basis and was not the result of any term in the Albacom 
        investment agreement. Following regulatory approval and consummation of 
        the proposed deal,  BT expects to consolidate the results of Albacom in 
        its Financial Statements from the date of acquisition.
