Resignation and Conviction Details
Sir Keir Starmer faces his first by-election test after disgraced MP Mike Amesbury announced he would quit Parliament following his conviction for assault. The ex-Labour politician was sentenced to 10 weeks in jail, later suspended on appeal, for punching a constituent in a late-night street bust-up.
Pressure on Sir Keir Starmer
The resignation hands Nigel Farage’s Reform a golden shot at snatching the seat, piling pressure on Sir Keir to fend off a major challenge in his first electoral test. Amesbury was also ordered to complete 200 hours of unpaid work, observe a 12-month alcohol monitoring program, and undergo 20 rehabilitation activity requirement days, including an anger management course.
Resignation Announcement and Regrets
Amesbury, who secured a 14,696 majority in Runcorn and Helsby, pleaded guilty in January and confirmed he would step down. He expressed regret for the assault and stated that he would have tried to remain as an MP if given a lighter community sentence.
Judge's Comments and Rehabilitation
After freeing the disgraced MP, Judge Steven Everett mentioned that Amesbury had lost his temper "in a huge way" and that the case portrayed him in a "truly unfavorable light as an MP." However, the judge also noted a potential for rehabilitation, leading to the suspended sentence.

Impact on Labour and By-Election Implications
Amesbury's resignation not only affects Labour but also opens the door for Nigel Farage's Reform to challenge for the seat, intensifying the pressure on Sir Keir Starmer and setting the stage for a significant by-election confrontation.
