Grant Shapps has quit as international development minister amid claims he failed to act on allegations of bullying, Downing Street has said.
Claims have engulfed the Conservatives following the apparent suicide in September of a youth activist.
Mr Shapps told the prime minister the "buck should stop with me" concerning issues while he was party co-chairman.
Youth organiser Mark Clarke has rejected allegations of bullying, sexual assault and intimidation.
He had been in charge of a campaigning initiative called RoadTrip which bussed young volunteers around the country.
The party has been subject to allegations since Elliott Johnson, 21, was found dead.
