Melvyn Bragg has stepped down from the BBC Radio 4 series In Our Time after hosting more than 1,000 episodes.
The veteran presenter, 81, has hosted every episode of the programme since it first launched in 1998, taking listeners through conversations with expert guests to explore characters, events and discoveries that shaped the world.
After more than two decades on the programme, Lord Bragg will leave the show, but will continue to work for BBC Radio 4.
He said: 'For a programme with a wholly misleading title which started from scratch with a six-month contract, it's been quite a ride!
'I have worked with many extremely talented and helpful people inside the BBC as well as some of the greatest academics around the world.
