Two stories about BBC Radio 1 - Chris Moyles and Nick Grimshaw

Today there are two stories about BBC Radio 1. Chris Moyles announcing that his record breaking show is coming to an end. And Nick Grimshaw is the new presenter of the Radio 1 Breakfast Show.

I've known Chris since he walked into Radio 1 in 1997. I was his producer on the Early Breakfast Show. I'm a fan of the Chris Moyles Show. And quite simply, he is the most successful breakfast show DJ in Radio 1's history. But he has done the show for over eight and a half years - he couldn't do it for ever - and I would rather he went out at the top of his game.

Added to that, this is just as much about Nick. He's a young star who is on the up. He loves his music, from Azealia Banks to One Direction. He has a great sense of humour, which comes across when interviewing either film stars or callers to the show. Plus, he can just about get away with using the word 'sick'. So, I believe the time is right to give him a new, bigger platform.

I wanted to surprise people today. There has been so much speculation over the years, almost as soon as Chris got the Breakfast Show, people were saying it would be soon over. But he not only survived the odd controversial moment, he also got record audience figures, loads of awards - including a Sony Gold - and has been entertaining over seven million listeners every morning.

I have said all along that when the moment came for the show to end, it would be a conversation between myself and Chris. It was. Chris wanted the Radio 1 listeners to be the first to hear, and to hear it from him. I'm glad in these days of instant news and social media, that this is what happened at 8 o'clock this morning.

I would like to thank Chris and the Team, and to congratulate Grimmy.
