Steven Woolfe injured himself falling backwards through a door rather than as a result of a punch to the face, an official Ukip investigation into a reported fight between two of the party's MEPs has found.

The report ruled it "impossible" to say for sure what happened when the two men stepped into a private room where the altercation took place and concluded that no further action should be taken against Mike Hookem, who is said to have struck the blow.

The findings are highly critical of Mr Woolfe, citing his lack of apology for the incident and the fact that he spoke extensively to the media in the aftermath as reflecting poorly on his character.

The official party report also states that a majority of those present believed Mr Woolfe was asking for a "physical altercation" when he demanded Mr Hookem join him outside during a meeting.
