Under-fire Labour MP Mike Amesbury has been suspended from the party and has had the whip withdrawn after fresh footage emerged of his altercation with a constituent.

In footage unearthed by the Mail, Amesbury was seen landing a sucker-punch on a man before beating him six times.

Just seconds before Labour's announcement, Reform UK, which came second in Amesbury's seat in July, called on Amesbury to resign.

A Reform UK Spokesman said: "The new footage of Mike Amesbury MP is damning.

"Reform UK are today calling for Mike Amesbury to do the honourable thing and resign," the party said

"No matter what verbal exchanges happened before, it's never acceptable for anyone to resort to violence to solve a dispute, let alone a sitting Member of Parliament.

"It's quite clear that the people of Runcorn and Helsby deserve far better than this.

"Reform UK are today calling for Mike Amesbury to do the honourable thing and resign immediately so a by-election can be held."

Practically seconds later, a Labour spokesman said: "Mike Amesbury MP has been assisting Cheshire Police with their inquiries following an incident on Friday night.

"It's quite clear that the people of Runcorn and Helsby deserve far better than this," Reform UK has said

Reform - whose candidate Jason Moorcroft came second in Amesbury's constituency - has called for an urgent by-election

"As these inquiries are now ongoing, the Labour Party has administratively suspended Amesbury's membership of the Labour Party pending an investigation."

A Cheshire Police statement on the incident - before the Mail's footage came to light - reads: "At 02.48am on Saturday, October 26, police were called to reports of an assault in Frodsham.

"A caller reported he had been assaulted by a man in Main Street. Enquiries are ongoing."

Then, posting on his own Facebook page on Saturday, Amesbury wrote: "Last night I was involved in an incident that took place after I felt threatened following an evening out with friends.

"This morning I contacted Cheshire Police myself to report what happened. I will not be making any further public comment but will of course cooperate with any inquiries if required by Cheshire Police."
