The 1965 act amended the
Homicide Act 1957, which had already reduced hangings to only four or fewer per year. The 1965 act was introduced to Parliament as a
private member's bill by
Sydney Silverman MP. The act provides that charges of
capital murder at the time it was passed were to be treated as charges of simple murder and all sentences of death were to be commuted to sentences of life imprisonment. The legislation contained a
sunset clause, which stated that the act would expire on 31 July 1970 "unless Parliament by affirmative
resolutions of both Houses otherwise determines". Resolutions were passed in the Commons and Lords on 16 and 18 December 1969, thereby making the act permanent. ==Subsequent events==
