Tony and Cherie Blair have been asked to appear on ITV1's Who Wants To Be A Millionaire?

Producers want the former Prime Minister and his wife to appear in a special Christmas edition of the quiz show, which will raise money for charity. The Blairs have not yet made a final decision on whether to sign up.

A show insider told The Mirror: "Some of our biggest celebs have appeared. Who knows - you are talking about two intelligent people - they could go all the way."
