Composition of the House of Commons after the election
Wilson decided to call a snap election since his government, elected a mere 17 months previously, in 1964, had an unworkably small majority of only four MPs. The Labour government was returned following this snap election with a much larger majority of 98 seats. This was the last general election in which the voting age was 21; Wilson's government passed an amendment to the Representation of the People Act in 1969 to include eligibility to vote at age 18, which was in place for the next general election in 1970.
