Mark Damazer has been appointed the controller of BBC Radio 4 and BBC7, the broadcaster has announced.
Mark Damazer has also been the BBC's head of current affairs
Mr Damazer is currently the deputy director of BBC News, and has also been the BBC's head of political programmes and head of current affairs.
He replaces Helen Boaden, who this week took up her new post as the director of BBC News, after four years as the controller of Radio 4.
He said: "Being controller of Radio 4 is the best job in broadcasting.
"Radio 4 is in terrific shape and my challenge is to cherish it, sustain it and make sure it remains the home for intelligence, flair and wit.
"BBC7 has already made a name for itself and I hope to see it become a must for those who value the BBC's storehouse of drama and comedy," he added.
The BBC's director of radio and music, Jenny Abramsky, described Mr Damazer as "a passionate listener and supporter of Radio 4".
"His first job in the BBC was as a current affairs radio producer in World Service, and since then he has worked in virtually every area of News and Current Affairs, winning a number of RTS Awards for his work," she said.
Ms Abramsky said Mr Damazer had looked after "some of radio's most treasured programmes" including From Our Own Correspondent and Analysis and would be an "inspirational leader".
"When you talk to him you realise it's in his blood. I'm sure he will build on Helen Boaden's success and take Radio 4 and BBC7 to new heights," she said.
BBC Radio 4 has 9.5m listeners and has an 11% share of the listening audience, while BBC7 is the newest digital radio network from the corporation.
It broadcasts comedy, drama and readings from the archives and children's programmes.
