Steven Woolfe is responsible for “instigating” an altercation with fellow MEP Mike Hookem which left him in hospital, a Ukip investigation has found.
The party has issued Mr Hookem with a “formal reprimand” over the altercation in Strasbourg earlier this month but will not formally suspend him.
Following the alleged altercation, 49-year-old Mr Woolfe was rushed to hospital after collapsing and suffering seizures. He claimed that Mr Hookem punched him, which he in turn denied.
The report states that because there were no eyewitnesses, it cannot be sure exactly what happened when the two men went outside the conference room together during a heated argument.
Mr Woolfe insists a blow from Mr Hookem knocked him back into the meeting room. However, the report described his version of events as “unlikely”.
It claims: “Mr Woolfe instigated the altercation by suggesting that he and Mr Hoookem deal with their differences “man to man”.
“Mr Hookem failed to give due consideration to the reputation of the party when deciding to accept Mr Woolfe’s suggestion.”
The report, published following an internal inquiry, adds that Mr Woolfe would have been facing a disciplinary panel over comments made to the Daily Mail in the wake of the incident had he not already quit.
It comes after both MEPs were reported to French police by the President of the European Parliament, Martin Schultz.
Mr Schulz said he referred the "regrettable" incident to the authorities after a recommendation from the European Parliament's advisory committee on conduct.
He told the parliament: "(The committee) concluded that the versions of the facts given by the two members involved diverged substantially and the facts seem to have happened in the absence of direct witnesses.
"It also stressed that given the seriousness of the reported facts and their possible criminal implications, further evidence is needed to clarify this matter.
"As a result I have decided to follow the recommendation of the advisory committee and I have referred this matter to the competent French authorities.
"Based on the result of the investigations I will then take a decision about a sanction to be imposed.”
