The son of Brigadier General Walter Allason DSO & Bar by his wife Katherine Hamilton Poland, daughter of Vice-Admiral James Augustus Poland, James Allason was raised primarily by a great-aunt following the death of his mother in 1913 protecting the infant James in a fall down stairs. Walter Allason was grandson of the architect Thomas Allason. He was educated at Haileybury and Imperial Service College and the Royal Military Academy, Woolwich. He served as an officer in the British Army for 24 years from 1930 to 1954, including in India, Ceylon and Burma, rising to the rank of Lt-Colonel. He joined the Royal Artillery in 1932 transferring to the 3rd Carabiniers in 1937. A gifted mathematician, he addressed the problem of using magnetic compasses with tanks: the Allason Sun Compass was adopted for use throughout the Asian theatre. Allason worked with the Supreme Allied Commander, Lord Louis Mountbatten, as joint planning staff officer in South East Asia Command and was wounded while commanding tanks during the Burma campaign. He was later decorated. He subsequently occupied a similar post as senior military planner at the War Office in London, answering Churchill's queries and providing briefings in the Cabinet War Rooms. His last planning task was to advise on the logistics of withdrawing from Palestine. From 1950 to 1954, he served at the War Office in charge of Army discipline.
Political career
After leaving the Army Allason worked as a Lloyd's of London insurance broker. He was elected a councillor on Kensington Borough Council in 1956. Allason contested Hackney Central in 1955. He was Member of Parliament for Hemel Hempstead from 1959 to 1974, when, following boundary changes, he narrowly lost the seat in the October election of that year to Labour's Robin Corbett. In government he was acknowledged for his expertise not only on defence but in the arcane but key subject of pensions. As Parliamentary Secretary to the Minister for War he had a ringside seat as the Profumo affair unfolded, refraining from publishing his inside account until after the death of Jack Profumo in March 2006. When the Conservatives were in opposition Allason was front bench spokesman on Housing for six years, and is credited with development of the policy of enabling council house tenants to purchase their own properties: this was taken up by Margaret Thatcher and adopted by subsequent Conservative governments, contributing to their electoral victories. After leaving Parliament he continued to exercise a rational influence on environmental policy from positions on the executive of the Town and Country Planning Association and the Environment Council's Transport Committee. Following the deaths of Patrick Maitland, 17th Earl of Lauderdale in December 2008 and Bert Hazell in January 2009, Allason became the oldest living former British Member of Parliament.
Personal interests
As a sportsman he raced Bentleys at Brooklands, played polo with maharajahs in India, skied and sailed in international competition, and represented the House of Commons in five sports. He continued skiing until his 87th year, and continued to play Contract Bridge and attend the Opera, on which subjects he wrote. In 1946, he married Nuala, daughter of John A. McArevey, of Foxrock, Dublin. They had two sons, the younger of whom, the Intelligence historian Rupert Allason, followed him into Parliament as Member for Torbay. Julian, the elder son, was a photographer and travel-writer, as well as vice-president of the Anthony Powell Society. The marriage was dissolved in 1974. His wife continued to live at what had been their family home at 15 Cheyne Walk in Chelsea. Allason also lived at Pump Lane House, Bembridge, Isle of Wight.
