Born in Cardiff, the younger son of John Bell, the young Bell was educated at Cardiff High School and Magdalen College, Oxford, graduating BA in 1936 and MA in 1941. In 1935, he was first Secretary and later Treasurer of the Oxford Union Society, and was also President of the Oxford University Conservative Association. In 1954 he married Elizabeth Audrey, eldest daughter of Kenneth Gossell MC, of Burwash, Sussex, and by her had two sons, Andrew and Robert, and two daughters, Fiona and Lucinda. Lady Bell died on 13 May 2014, aged 86.
Bell was an early and very active senior member of the Conservative Monday Club, and led the rebels in the House of Commons against the Race Relations Act 1965. He argued against the importing of a new law affecting freedom of speech, and freedom to employ whoever one wishes, and, supported by Enoch Powell, said the Bill made "very deep and damaging encroachments into the proper sphere of personal decision". He also felt that the Bill was an effort to achieve unwarranted equality, and that it was "concerned solely and exclusively with the intention to achieve social equality". In a vote on 22 December 1964, Bell was one of the 91 Tory MPs to vote in favour of the abolition of the death penalty. On May Day 1970, he was one of the principal politicians to speak at the Monday Club's "Law and Liberty" rally in Trafalgar Square, London, in opposition to the "Stop the Seventy Tour" campaign aimed at stopping that year's South African cricket tour. Bell was still a member of the Monday Club's Executive Council in 1971 and 1972; and in September 1972 he was a principal speaker at the Club's "Halt Immigration Now!" rally in Westminster Central Hall, following which a resolution was passed calling upon the government to halt all immigration, repeal the Race Relations Act, and start a full repatriation scheme. That was delivered to Edward Heath, then Prime Minister, who said that the government had no intention of repealing the Act. In 1972, Bell and Powell were the leaders of an open rebellion against the leadership of Edward Heath, who retaliated against Bell by attempting to have him replaced as the Tory candidate for Beaconsfield by Michael Heseltine, whose own seat at Tavistock was due for abolition in the current round of boundary changes and agreed to seek the nomination. A struggle within the local Conservative association ensued in which Bell's campaign was successfully masterminded by Hugh Simmonds, chairman of the Young Conservatives. Bell was opposed to the entry of Ugandan Asians into Britain, stating that "They were either born in India or retain a close connection with India, they have no connection to Britain by either blood or residence." In January 1973, Bell and Powell were opponents of Heath's Counter-Inflation Bill, with Bell arguing that prices and incomes policies were incompatible with the British way of life and were not Conservative measures. At the same time, Nicholas Ridley complained that what was needed was a "proper economic policy", and Richard Body stated that the real cause of inflation was too much government spending. In 1975, Bell supported Margaret Thatcher's successful challenge to Heath's leadership of the party.
