Leukaemia Research has welcomed the prospect of working more closely with Alastair Campbell following his resignation as Downing Street's head of communications.
Campbell has said that he would like to do more work with the charity when he leaves his job in a few weeks' time. He raised £320,000 for the charity by running this year's London Marathon, with celebrity and political sponsors including US President George Bush.
The charity's chief executive Douglas Osborne said: "Like most of our supporters, Alastair's involvement with Leukaemia Research comes from deep, personal commitment to our cause. I have no doubt that he will continue to be an incredibly effective fundraiser for us in years to come."
