Mike Amesbury was suspended from Labour after CCTV and video footage showed him throwing a punch at a man in October and repeatedly hitting him after the man was knocked to the ground.

Amesbury, the MP for Runcorn and Helsby in northwest England, said he felt threatened on the street after an evening out with friends.

The 55-year-old appeared at Chester magistrates’ court on Monday, where his lawyer Stephen Derby said Amesbury was remorseful and had apologised for his actions.

Amesbury was sentenced to 10 weeks for a single count of common assault, having pleaded guilty last month.

Judge Tan Ikram said: “An immediate custodial sentence is, in my judgment, both necessary as a punishment and a deterrence.”

The judge added that Amesbury would serve 40% of the sentence in custody.

Lawmakers convicted of an offence and given a jail sentence or a suspended jail sentence can potentially be removed from office if enough constituents support a petition calling for a new election for their parliamentary seat.

Any such vote would put pressure on Labour, led by Prime Minister Keir Starmer, following the party’s landslide national election win in July.

Amesbury won the seat comfortably for Labour last year but since then the right-wing Reform UK party, led by Nigel Farage, has overtaken Labour in some national opinion polls.
