Nick Grimshaw has said he was "nervous and excited" to take over Radio 1's Breakfast Show.
Chris Moyles has been given a send-off by showbiz pals including Ant and Dec who hosted a This Is Your Life-style farewell.
Nick Grimshaw has been handed the flagship Radio 1 breakfast show after Chris Moyles announced on air today that he was bowing out.
Nick Grimshaw has increased his Radio 1 Breakfast Show audience, but is still almost four million listeners behind his Radio 2 rival Chris Evans.
Grimshaw, who replaced Chris Moyles last year, saw his average audience reach 5.88 million according to industry body Rajar.
But is still less than Radio 4's Today Programme, which had an average audience in the second quarter of this year of 6.97 million, and way behind Evans whose average audience was 9.75 million.
DJ Tim Westwood is set to leave Radio 1 after almost 20 years as part of a shake up of the station's schedule.
The 55-year-old - affectionately known as Big Dawg - currently hosts a two-hour Saturday night show, broadcast on Radio 1 and 1Xtra.
Radio 1 controller Ben Cooper paid tribute to Westwood's 20 years service: "I'd like to thank Tim for the last 20 years on Radio 1. His passion for hip hop is legendary. I wish him all the very best."
The Presenter was injured in a drive-by shooting in south London in 1999 after a gunman opened fire on his stationary Range Rover.
Reggie Yates and Vernon Kay are to leave BBC Radio 1. Radio industry website Radio Today says the changes are part of an overhaul the station’s weekend schedule.
Radio Today reports Jameela Jamil will take over from Reggie while Matt Edmondson moves into the weekend 10am-1pm slot.
