He'll be presenting 'On Your Marks', the station's breakfast show Monday to Friday from 7-11am.
Derek says "I was so pleased to be asked by my friends that run the station to join and I've loved what I've heard so far. A lot of people think that it might be non-stop Kylie or Chaka Khan, but Diva means any music that is big or iconic. I'm really looking forward to joining the team and playing loads of brilliant music. The station isn't full of ads, news, sport and chatter - so it's the kind of listen that you can enjoy clutter-free everywhere'.
