Having gained a place in the Parliamentary Labour Party, Mosley swiftly rose up the ranks, closely aligning himself with leader Ramsay MacDonald. In the years of opposition in the late 1920s, Oswald Mosley was called upon to define a prospective Labour Government’s economic philosophy. These tenets became known as the Birmingham Memorandum. While the programme was not enthusiastically received by the Labour Leadership, his support among younger MPs and the wider membership led to him being appointed Chancellor of the Exchequer in the 1929 Labour administration.
