Hamilton argued for the individual's right to smoke. He was the only member in committee to oppose the Conservative government's bill to outlaw trafficking in human organs. In April 1986, Hamilton was one of ten MPs to vote against the government on an EEC bill. Hamilton was a member of the "No Turning Back group", a part of the Conservative Party calling for the privatisation of schools and the National Health Service, which he described as "vast monoliths". In November 1989, Hamilton won the "Spectator" parliamentary wit of the year award. He jokingly remarked that when told of winning the award, he thought it was for being the "Twit of the year". Hamilton's comments are frequently controversial. During a debate about amputees he said that Frank Dobson "does not have a leg to stand on". (January 1987). To Jeremy Corbyn, he suggested that "some of [his] IRA friends could be used to get rid of pensioners by shooting them"—also in 1987. On 4 June 1983, five days before polling day in the 1983 general election, Hamilton married Mary Christine Holman, the secretary to Tory MP Michael Grylls, in Cornwall. In September 2003, after having a residence in the Tatton constituency for twenty years, the Hamiltons moved to Hullavington, Wiltshire, where they purchased a home in October 2004. Since 2008, he has been company secretary of Vixen Consultants Limited. The trading name of Vixen Consultants is Christine Hamilton.
