Sir Dennis Murray Walters MBE (born November 1928) was a British Conservative Party politician. He was the Member of Parliament (MP) for Westbury from 1964 to 1992.
The son of Douglas Walters and Clara Pomello, Walters was of English and Italian descent and was brought up as a Roman Catholic. At the outbreak of the Second World War he was in Italy and was interned, but after the Armistice of 1943 he was released and served for eleven months with the Italian Resistance. He then returned to England and was educated at Downside School and St Catharine's College, Cambridge, where he read Modern Languages.
In the late 1950s, Walters was employed as personal assistant to the Conservative peer Lord Hailsham throughout his chairmanship of the Conservative Party. In 1960, he was appointed MBE for political services.
At the 1959 general election, Walters contested Blyth for the Conservatives, fighting the seat again the next year at a by-election after Alf Robens was promoted to the House of Lords. In October 1962 he was selected as his party's candidate for the safe seat of Westbury, which he represented as Member of Parliament (MP) for 28 years from 1964. During his early years in the Commons he worked closely with Shadow Foreign Secretary Sir Alec Douglas-Home, of whom he later wrote "I could not imagine a more considerate, fair, or civilised person to serve."
