                           Total Voting Rights Update


In conformity with the Transparency Directive, we would like to notify the
market of the following:

The Company's issued capital consists of 60,332,284 ordinary shares of 0.25
pence each ('Ordinary Shares'), all with  voting rights.  No shares were held in
treasury at the date of this announcement.  The total number of current voting 
rights in the Company is therefore 60,332,284.

The above figure (60,332,284 Ordinary Shares) may be used by shareholders as the
denominator for the calculation by  which they will determine if they are
required to notify their interest in, or a change in their interest in, the 
Company under the FSA's Disclosure and Transparency Rules.
