1965 Leyton by-election
The seat had become vacant when the constituency's long-serving Labour Member of Parliament (MP), Reginald Sorensen, was made a life peer on 15 December 1964. An MP for over thirty years, his elevation to the peerage was intended to create a vacancy in a safe seat for the Foreign Secretary, Patrick Gordon Walker, who had been defeated in a shock result in the 1964 general election in his Smethwick constituency.
The result of the contest was not as planned: the Conservative Party candidate, Ronald Buxton, won with a majority of 205 votes, a swing from Labour of 8.7%. Gordon-Walker regained the seat for Labour at 1966 general election.
