Ken Bruce of BBC Radio 2 has announced on air that he is leaving the station after 31 years hosting its weekday mid-morning show.
His slot is the most listened-to show on British radio, and he will now join rival station Greatest Hits Radio.
“I have decided the time is right for me to move on from Radio 2,“ he said, adding he’d had “a tremendously happy time” but it was “time for a change”.
His departure comes after Steve Wright left after 23 years as afternoon host.
Other popular presenters who have also left the station in the past year include Paul O’Grady and Vanessa Feltz.
Bruce told listeners: “I’ll reach the end of my current contract in March, and so at that point I will be moving on from Radio 2. Nothing stays the same forever…
“I have been here for quite a long time now, and it possibly is time to move over and let somebody else have a go.”
His programme, well known for its daily Popmaster quiz, currently has more than 8.5 million weekly listeners, according to data from industry body Rajar.
One of the station’s longest-serving hosts, he joined the BBC in 1977 and took his first regular Radio 2 slot in 1984.
