The company said that, subject to Dr McAdam’s election by shareholders at the United Utilities’s annual general meeting (AGM) on July 25, 2008, he will take over from Sir Richard Evans as chairman of the board at the AGM. This follows Mr Evans’s decision to step down as chairman and a director of United Utilities following the 2008 AGM.

Dr McAdam was a non-executive director of Severn Trent between 2000 until 2005. He is currently a non-executive director and senior independent director of J Sainsbury; a member of the University of Cambridge chemistry advisory board; and formerly a member of the University of Surrey Business advisory board.

Mr Evans said: I have very much enjoyed my 10 years on the board of United Utilities, seven of which were as the company’s chairman. I now believe the time is right to step down. I am delighted that, in John McAdam, we have found such a strong successor.
