 After the war Stevenson stood as the Conservative Party candidate to represent Maldon in the 1945 United Kingdom general election.He opened his campaign by declaring that in the interests of a clean fight, he would make no allusions to the "alleged homosexuality" of his opponent, Tom Driberg, who heavily defeated him in the vote; Stevenson returned to his legal practice the following year.Despite his severe manner, Stevenson was extremely sociable and he was often the centre of a lively crowd at the bar of the Garrick Club, of which he was a member.
