The murder of John Alan West on 7 April 1964 was the crime which led to the last death sentences being carried out in the United Kingdom. West, a 53-year-old van driver for a laundry, was beaten and stabbed to death by Gwynne Evans and Peter Allen, who had gone to rob him at his home in Seaton, Cumberland. Both murderers were unemployed, had a history of petty crime and were arrested and charged within two days of the crime. At trial, each blamed the other, but the jury found both men guilty, and both were sentenced to death.

The use of capital punishment in the United Kingdom had been declining at the time, and public opinion was turning against the practice. As a result, the decision not to reprieve the two condemned came as a surprise. Both were executed at 8:00 am on 13 August 1964, in prisons in Manchester and Liverpool. Capital punishment for murder was abolished in the United Kingdom 15 months later.
