1920s and 1930s Greenwood was first elected to the
House of Commons at the
1922 general election for the constituency of
Nelson and Colne in
Lancashire. Greenwood was an active
freemason, associated with the
New Welcome Lodge. In 1924, when the short-lived
first Labour government was formed under
Ramsay MacDonald, Greenwood was appointed as
Parliamentary Secretary to the Ministry of Health, under
John Wheatley, and he helped to draft the
Wheatley Housing Act. On 2 September 1939, acting for Attlee who was in hospital for
prostate surgery, he was called to respond to
Neville Chamberlain's ambivalent speech on whether Britain would aid Poland. As he was about to speak, he was interrupted by an angry Conservative backbencher and former
First Lord of the Admiralty,
Leo Amery, who electrified the chamber when he exclaimed loud and clear: "Speak for England, Arthur!" A flustered Greenwood proceeded to denounce Chamberlain's remarks, to the applause of both sides of the House, in a short speech for which he is best remembered.
Wartime government In the opening months of
World War II Greenwood played a central role in Labour's strategy of supporting the war effort but refusing to serve in a government under Chamberlain. Greenwood however was in decline by this time, judged by Churchill to be ineffective, he was sacked from the cabinet in February 1942. From February 1942 until the end of World War II, Greenwood performed the function of
Leader of the Opposition, though he did not receive the salary. In 1943, he was elected as
Treasurer of the Labour Party, beating
Herbert Morrison in a close contest.
Postwar During the
Attlee government, he served successively as
Lord Privy Seal,
Paymaster General and Minister without Portfolio. According to one historian, he was a major architect of both the
National Health Service and the
national insurance system through his chairmanship of the cabinet social services committee. In September 1947 Attlee sacked him from the cabinet in a reshuffle, on the basis that he wanted to bring in younger men. He continued to be elected to positions in the Labour Party, retaining the post of Treasurer until 1954, and being elected as
Chair of the National Executive Committee in 1952. == Personal life ==
