The Radio 2 Drivetime show with Simon Mayo and Jo Whiley is to end after just a few months on air.
Mayo is leaving BBC Radio 2 altogether but will continue to present his 5 Live film show with Mark Kermode.
Whiley will remain on Radio 2 but move to the 7-9pm slot.
Mayo has presented Drivetime for eight years, but the station added Whiley as a co-host in June – a move which led to huge backlash from listeners.
Simon said: “Obviously, I’m very sad to be leaving Radio 2, and my good friend Jo. However, 2019 looks like being incredibly exciting for me.
“I have a new two-book deal with Transworld, my children’s series Itch is being filmed for TV in Australia in early 2019, and I’m continuing to develop my novel Mad Blood Stirring for a movie with screenwriter Jack Thorne.
“Plus the film show with Mark Kermode continues on 5 Live.”
Jo Whiley said: “I’m incredibly sad that Simon has decided to leave Radio 2. He’s a brilliant broadcaster, a great friend and I really will miss working with him.
“However, I’m very much looking forward to hosting a new show for a new year which will have music at the very heart of it as well as guests and live sessions. Dream show, actually. Can’t wait!”
The new look Drivetime show, which started in January, left a lot of listeners feeling disappointed.
So much so, that Radio 2 had to offer an official response to complaints.
“We acknowledge some regular listeners are unhappy with the changes,” Radio 2 said at the time.
“Every new show needs time to settle down and so we hope listeners will continue to listen and give it a chance.”
