The infamous Who Wants To Be A Millionaire? cheating scandal is being adapted into a TV drama starring Matthew Macfadyen and Michael Sheen - with the latter playing quiz show host Chris Tarrant.

Macfadyen will play Charles Ingram, the so-called 'Coughing Major', in Quiz, with Fleabag actress Sian Clifford in the role of his wife Diana.

The drama will air on ITV, which broadcasts Who Wants To Be A Millionaire? - which is said to be the "most successful game show of all time".

Former British Army major Ingram, who won the top prize on the show in 2001, was found guilty in 2003 of cheating his way to the £1 million prize.

Ingram listened for coughs from college lecturer Tecwen Whittock, who sat in the studio audience, to steer him to the correct answers. Michael Jibson plays Whittock on the show.

The drama is directed by Stephen Frears, whose film credits include A Very English Scandal and The Queen.

Helen McCrory, Mark Bonnar and Aisling Bea will also star in the production, penned by James Graham, whose play of the story hit the West End.

The playwright said: "I was gripped by this story over 15 years ago, and I'm still gripped now. It's a very English heist."

ITV's head of drama Polly Hill said the three-part series would be "an extraordinary and thoroughly British story and is going to be a real treat for our audience".
