Former Radio 2 presenter Ken Bruce has spoken for the first time about the real reasons he quit the station, saying he disliked some of the new music he was forced to play and feared being seen as a ‘grumpy old man’ by younger colleagues.

The veteran broadcaster was pulling in 8.3 million listeners to his BBC programme until he left in March for commercial rival Greatest Hits Radio, where he has increased the mid-morning audience by more than 1.25 million.

Meanwhile, his old Radio 2 slot, now filled by Vernon Kay, lost 1.4 million listeners in its first three months without him.

Previously, the 72-year-old said he left the BBC after three decades in the same slot because it was ‘time for a change’ and it felt ‘like the natural culmination of some planning I’ve been doing’.

But now he has revealed he decided to jump ship before he started to become ‘bitter and entrenched’, saying: ‘It was a long time and I thought I’m doing the same thing every day.
