Yet the real reason is more likely to lie in his entrepreneurial ambition. A combative interviewee - who rarely talks to journalists - he attracts admiration and scepticism in equal measure.
His critics acknowledge the drive and determination of a self- made man, but worry that he is more interested in turning Carlton Communications into an international media empire than in quality programme making.
Born in north London to middle-class parents - Cyril Green, who built up the Tern shirt company, and Irene, a psychologist - he left school with four 'O' levels.

An early run-in with television was in 1985, when he attempted a bid for Thames. That ambition went unsatisfied until 1991 when he outbid the group for the London weekday franchise.
He is no stranger to political controversy. After it was alleged he had given pounds 15,000 to the Conservative Party, it was suggested that he should be barred from the chairmanship of ITN.Reuse content
