The Company confirms that the Tender Offer announced by the Company on
16 May 2011 completed today. Under the terms of the Tender Offer, J.P. Morgan
Cazenove purchased 65,911,929 ordinary shares at a price of 625 pence per
share. Such shares were subsequently acquired from J.P. Morgan Cazenove by the
Company under the terms of the Option Agreement at a price of 625 pence per
share. The purchased shares will be cancelled.

Following the above transaction, and in accordance with DTR 5.6.1A, the
Company's issued share capital consists of 474,911,204 ordinary shares, all of
which carry voting rights. The Company does not hold any shares in treasury.
Therefore, the total number of voting rights attaching to shares in the Company
is 474,911,204.

The above figure (474,911,204) may be used by shareholders as the denominator
for the calculations by which they will determine if they are required to
notify their interest in, or a change to their interest in, ordinary shares to
the Company under the FSA's Disclosure and Transparency Rules.

Capitalised terms used in this announcement shall have the same meaning
ascribed to them in the Tender Offer circular published by the Company on
16 May 2011.
