He found a living as a financial journalist on the staff of the Evening Standard. When the Second World War broke out, Aitken joined the Royal Air Force and piloted fighter reconnaissance aircraft; he was severely injured in 1945 and invalided out. His son Jonathan Aitken, later a politician, was born in 1942, and his daughter Maria Aitken, later an actress, was born in 1945. Penelope Aitken became a leading socialite in post-war society. His grandson, Jack Davenport, became an actor.
Career
At the 1945 general election, Aitken was the Conservative Party candidate who attempted to recapture West Derbyshire; he lost by only 156 votes. He became instead Manager of London Express News and Feature Services while he searched for another Parliamentary nomination. He was also a director of Shop Investments Ltd and Western Ground Rents Ltd, both of which were property investment companies.
Parliament
In 1948, Aitken was adopted as Conservative candidate for Bury St Edmunds in Suffolk, in succession to Geoffrey Clifton-Brown who was standing down. At the 1950 general election, Aitken was elected by 4,129 votes. In Parliament, Aitken showed a particular interest in Commonwealth issues, and was elected Vice-Chairman of the Conservative Commonwealth Affairs Committee. In 1951 he called for reform of the House of Lords so that it included representatives of the Colonies, Dominions and states of the Commonwealth. Aitken was a rare speaker, choosing to intervene only in those debates where he had a particular knowledge. He remained a backbencher although he was a member of the round-table conference on the constitution of Malta in 1955. His support for the Commonwealth made him distrust attempts to have the United Kingdom sign the Treaty of Rome. His most famous action in Parliament was to introduce his Private Member's Bill of 1961, the Highways Bill, which gave local authorities more powers to remove obstructions to roads and to acquire land to build straight roads. In 1960 Aitken voted to support a Labour amendment to the Betting Levy Board to reduce the Jockey Club's members of the Horserace Betting Levy Board to one, on the grounds that there should also be a veterinary surgeon on the board. In 1962, Aitken was given the honour of moving the 'loyal address' after the Queen's Speech. He was made a Knight Commander of the Order of the British Empire in the Queen's Birthday Honours of 1963.
Death
He died suddenly in January 1964 aged 60. He is buried in the churchyard of St. Mary's, Playford, Suffolk.
