Member for Runcorn and Helsby quits two weeks after receiving a suspended sentence for punching a constituent

Mike Amesbury has resigned as an MP after being given a prison sentence for punching a constituent, triggering the first byelection of Keir Starmer’s government.

The Runcorn and Helsby MP was suspended by Labour and lost the party whip in October after a video of the incident on a night out was published online. He was given a 10-week prison sentence, suspended for two years.
