During the 1930s, with the Labour Party split and weakened, Bevin co-operated with the Conservative-dominated government on practical issues, but during this period he became increasingly involved in foreign policy. He was a firm opponent of fascism and of British appeasement of the fascist powers. In 1935, arguing that Italy should be punished by sanctions for her recent invasion of Abyssinia, he made a blistering attack on the pacifists in the Labour Party, accusing the Labour leader George Lansbury at the Party Conference of "hawking his conscience around" asking to be told what to do with it.
