After Dinner Speakers: Chris Tarrant, George (Snr) Bush, Kelly Brook

Love him or loathe him, with his popular breakfast show on Capital Radio and his regular peaktime appearances on ITV, Chris Tarrant has become the king of popular broadcasting. He may not be the most obvious media power broker, but he's the biggest personality on UK commercial radio and has done wonders for the popularity of ITV's Who Wants to be a Millionaire?, which is now the world's most successful quiz show. ITV has returned the favour by making Tarrant the biggest face on the box. Earlier this year he knocked Richard Madeley and Judy Finnigan off their thrones to become the most recognisable face on British TV. In May, Tarrant also picked up a Sony award for his "unique relationship with his listeners" but was also praised for still bothering to get up in the mornings when he already had more money than he needed. He started his career as an English teacher before he got his first TV break in Tiswas. After the show ended in 1982, he got involved in the adult version of Tiswas, OTT, which was one of the few Tarrant flops.
