A furious row has erupted at the heart of Ukip after its only MP and a millionaire donor clashed in a corridor at the party's annual conference.
Douglas Carswell accused Arron Banks of acting in an undemocratic manner by briefing journalists that he would be de-selected as the MP for Clacton unless he joined the businessman's campaign to leave the European Union.
Mr Banks called the incident a "hissy fit in a corridor" and refused to give Mr Carswell his backing.
But the MP insisted he had simply "politely and respectfully" asked the donor why he was threatening to oust him from the Commons.
The confrontation overshadowed Ukip leader Nigel Farage's keynote speech at the conference in Doncaster where he told activists that the new Leave EU umbrella campaign, led by Mr Banks, would unite eurosceptics.
