RADIO 2 Breakfast show host Chris Evans has announced he is leaving the station.

The broadcaster and his wife Natasha are expecting twins.

He was emotional as he told his listeners this morning: "The twins are on their way" adding: "I'm going to leave Radio 2."

He said: "Some of us are mountain climbers and if you get to the top of your favourite mountain, you become a mountain observer, so I've got to keep climbing."

He added: "You have to keep shaking it up."

BBC director general Tony Hall said: "Chris has been an absolutely first-class presenter of the Breakfast Show.

"He has brought both warmth and a genuine insight into what listeners want.

"He has given 100% to each of his BBC projects, including raising millions of pounds for Children In Need. I'd like to thank him for all his efforts over the years and wish him all the best for the future."
