A UKIP MEP who spent three nights in hospital after a row with a party colleague is quitting the party, saying it is in a “death spiral”.
Steven Woolfe, who had been running to be the next leader, told the BBC there was “something rotten” in the party.
He also accused fellow MEP Mike Hookem of inflicting a “blow” to his face in the row at a party meeting.
Mr Hookem has acknowledged a “scuffle” but said he “categorically did not” throw a punch at his colleague.
Mr Woolfe was rushed to hospital after collapsing following the incident, which UKIP described as an “altercation”, and came during a meeting to discuss reports the North West England MEP had had discussions about joining the Conservatives.
