He is one of only three people to have served as Home Secretary, Foreign Secretary and Chancellor of the Exchequer, the others being Rab Butler and James Callaghan.
He also served as Lord Chancellor, the most senior position in the British legal system. Beginning his career as a Liberal (identified initially with the left wing but later with the right wing of the party), he joined the National Government in 1931, creating the Liberal National Party in the process. At the end of his career, he was essentially a Conservative.
