Broadcaster Richard Bacon is leaving the BBC to replace DJ Neil Fox at London radio station Capital FM.
Richard Bacon will join Capital FM later this year
The BBC Radio Five Live presenter and former Blue Peter host will take over Fox's drivetime show from May.
He will be giving up his Radio Five Live weekend show after signing an exclusive deal with Capital.
Fox, who has presented the drivetime slot for eight years, said he was leaving the station to concentrate on TV projects.
Bacon, 29, said: "This is a great opportunity to do one of the main shows on a massive station."
Early last year Fox quit as the voice of commercial radio chart countdown Hit 40 UK after more than a decade.
He said: "I have been and always will be a radio man but I've got a lot of ITV shows coming up and I've learned you just can't do it all.
"I'm chuffed for Richard, he's a great broadcaster."
Capital boss Keith Pringle said: "I'm very excited about Richard joining Capital FM. He's a sparkling talent who is as smart as he is funny."
A spokesman for the BBC said: "Richard has been on Five Live for just over a year and has done a terrific job at the weekends.
"He is now out of contract with us and free to work wherever he likes, so we wish him well."
