The Crown Prosecution Service (CPS) is considering whether to lay charges against MP Mike Amesbury after video emerged of him appearing to punch a man to the ground.

A statement from Cheshire Police confirmed it had passed a case to the CPS after questioning Mr Amesbury about the incident last week.

Mr Amesbury, who represents Runcorn and Helsby, was suspended from the Labor Party last Sunday after a clip was published by MailOnline in which he can be seen continuing to punch the man, who is lying on the ground in while people nearby shout “stop it”.

He was not arrested but was interviewed under caution after attending a voluntary police interview last weekend.

On Friday, a Cheshire Police spokesman said: “Cheshire Police received reports of an assault in Main Street, Frodsham, at 2.48am on Saturday 26 October.

“An investigation was immediately launched and a 55-year-old man was voluntarily interviewed under caution by police in relation to this incident.

“A file was submitted to the Crown Prosecution Service on Tuesday 29 October for consideration and we await their decision.”

The CPS confirmed it had received a file but could not give a time frame for its decision on whether to charge Amesbury.

In a statement released shortly after the incident, Mr Amesbury said he had reported himself to police and would co-operate with their inquiries while remaining “an open and accessible MP to our community”.
