Veteran jazz musician and radio host Humphrey Lyttelton has died aged 86.

The chairman of BBC Radio 4's comedy panel show I'm Sorry I Haven't A Clue recently had surgery in an attempt to repair an aortic aneurysm.

The latest series of the quiz programme was cancelled after Lyttelton was admitted to Barnet Hospital in north London on 16 April.

BBC Director General Mark Thompson described "Humph" as "a unique, irreplaceable talent".
