Paul Gambaccini will not present the 22nd Music Industry Trusts (MITs) Award dinner in London tonight following his arrest last week.
BBC presenter Gambaccini, 64, was arrested by police as part of an investigation into historical sex offences.
UPDATE: Music Week understands that BBC Radio 2 presenter Jo Whiley will now host this evening's event.
Gambaccini was held at his home in south London early on Tuesday and questioned in police custody, before being released on bail until January.
He was due to host this evening's MITs gala dinner at the Grosvenor House Hotel, which will honour Annie Lennox for her outstanding contribution to British music and charity work.
A spokesperson for the presenter told the press: "I can confirm he has withdrawn from hosting the MITs."
In a separate statement, they said: "Mr Gambaccini was interviewed by Operation Yewtree officers about historic allegations. He answered their questions and was co-operative. He denied all allegations."
The BBC said Gambaccini would not be presenting his Saturday Radio 2 show for the coming weeks.
