Wilson had never made much secret that his support of the left-wing Aneurin Bevan was opportunistic. In early 1954, Bevan resigned from the Shadow Cabinet (elected by Labour MPs when the party was in opposition) over Labour's support for the setting-up of the Southeast Asia Treaty Organization (SEATO). Wilson, who had been runner-up in the elections, stepped up to fill the vacant place. He was supported in this by Richard Crossman, but his actions angered Bevan and the other Bevanites.
