Secretary, Ernest Bevin. Noel-Baker moved to become Secretary of State for Air in October 1946, and then became Secretary of State for Commonwealth Relations in 1947 and joined the cabinet. Noel-Baker was the minister responsible for organising the 1948 Olympic Games in London. He moved to the Ministry of Fuel and Power in 1950. In the mid-1940s, Noel-Baker served on the British delegation to what became the United Nations, helping to draft its charter and other rules for operation as a British delegate. He served as Chairman of the Labour Party in 1946–47, but lost his place on the National Executive Committee in 1948, his place being taken by Michael Foot. An opponent of left-wing Bevanite policies in the 1950s, and an advocate of multilateral nuclear disarmament, rather than a policy of unilateral disarmament, he received the Nobel Peace Prize in 1959. In 1979, with Fenner Brockway, he co-founded the World Disarmament Campaign, serving as co-Chair until he died, and was an active supporter of disarmament into the 1980s. Noel-Baker stood down as the MP for Derby South at the 1970 general election, at which he was succeeded by Walter Johnson. His life peerage was announced in the 1977 Silver Jubilee and Birthday Honours and, aged 87, he was raised to the peerage 22 July 1977, as Baron Noel-Baker, of the City of Derby, having declined an appointment as a Companion of Honour in the 1965 New Year Honours. He was president of the International Council of Sport Science and Physical Education from 1960 to 1976. Noel-Baker was an active contributor to House of Lords debates into his nineties, speaking in debates on the ongoing Falklands War in the months preceding his death. A memorial garden, the Philip Noel-Baker Peace Garden, exists within Elthorne Park, a small park in the London Borough of Islington. Personal life In June 1915, Philip John Baker married Irene Noel, a field hospital nurse in East Grinstead, subsequently adopting the hyphenated name Noel-Baker in 1921 by deed poll. His wife was a friend of Virginia Woolf. Their only son, Francis, also became a Labour MP and served together with his father in the Commons. Their marriage, however was not a success and Noel-Baker's mistress from 1936 was Megan Lloyd George, daughter of the former Liberal Party leader David Lloyd George, herself a Liberal and later Labour MP. The relationship ended when Irene died in 1956.
