Former GCap Media chief Ralph Bernard is to leave his chief executive role at the Royal Albert Hall and return to radio.
Bernard, who helped found Classic FM (and is still its chairman), took on his post at the Royal Albert Hall in March this year.
In a message to his staff as reported on the Guardian website, Bernard said the chief executive's role was not the job he expected it to be.
He added: "For many years the most senior role here was that of general manager and in my view that is in many ways what the role still is. And that's not me."
As well as founding Classic FM, Bernard was chief executive of the radio group GWR from 1982 to 2005, and helped engineer its merger with Capital Radio to create GCap Media.
His return to programme-making includes a project with Johnnie Walker for BBC Radio 2.
