Notification concerning realignment of interests in shares

1   We hereby give notice to the Company, pursuant to the provisions of Section
198 of the Companies Act 1985 (the "Act"), of the event referred to in paragraph
3 below.

2   This notice is given in fulfilment of, and for the express purpose of
discharging the obligations imposed on us and on certain investment companies
with variable capital ("ICVCs") by the said Section and arising out of the
transaction referred to in paragraph 3 below. A copy of the SAR 3 announcement
which was released to the Stock Exchange today is attached.

3   On 22nd September 2003 (date of conversion of unit trusts to ICVCs) we
ceased to be interested, within the meaning of Sections 203 and 208 of the Act,
in 135,204,937 ordinary shares of 25p each in the capital of the Company.

4   Immediately following the transaction referred to in paragraph 3 above, we
no longer had a notifiable interest (within the meaning of Section 199(2) of the
Act), in the ordinary shares of 25p each in the capital of the Company.

5   Immediately following the transaction referred to in paragraph 3 above and
the purchase of 250,000 shares on 25th September 2003, the ICVC named below had
a notifiable interest (within the meaning of Section 199(2) of the Act) in the
number of ordinary shares set out opposite their name, the registered holders of
such shares being as also indicated below.

ICVC                            Registered Holder          Number of     %

INVESCO UK Investment Series    Vidacos Nominees Limited   132,720,878   13.62*


6  None of these shares is beneficially owned by AMVESCAP.  Subsidiary companies
of AMVESCAP have a large number of portfolio management clients for whom they
act as investment manager and investment advisor and by virtue of Section 203
of the Act 1985 AMVESCAP is deemed to have the same interest in the shares.

7  This  is given by AMVESCAP for itself and as agent for the ICVCs named above.

* Based on an issued share capital of 974,053,189
