BBC Radio 1Xtra specialist music DJ Benji B is moving to BBC Radio 1 to host the Thursday 2-4am slot on the station.
He's replacing the slot left vacant by Mary Anne Hobbs, who leaves the station after 14 years to teach at the University of Sheffield.
Since Radio 1Xtra began broadcasting eight years ago, Benji has presented a weekly show on the station. His final Radio 1Xtra show will be on Sunday 10 October and he makes his Radio 1 debut on Thursday 14 October.
Benji B says: "I've loved every minute of my eight years at 1Xtra and am delighted to be given this incredible opportunity.
"I can't wait to bring the essence of my Sunday night show and my loyal audience to my new Radio 1 programme."
Ben Cooper, Deputy Controller, BBC Radio 1, says: "Benji B's reputation for finding and supporting new cutting-edge music is exemplary, and I'm excited about him being able to put his own mark on the slot by bringing some of the finest cutting-edge dub step and experimental electronica to our audiences."
With Benji B's move to Radio 1 there will be a new line-up of programmes on Sunday nights on Radio 1Xtra.
