Carlisle was elected as MP for
Lincoln at the
1979 general election, becoming the first Conservative to win the seat in 50 years.
The Almanac of British Politics noted that his win was helped by the presence of a candidate for the
Democratic Labour Party, which drew votes away from the incumbent
Labour MP
Margaret Jackson. In the 1980s he substantially increased his majority, thanks in part to the addition of several middle-class suburbs to the north of
Lincoln before the
1983 general election. He was a
Parliamentary Under-Secretary of State at the
Ministry of Defence from October 1990 - March 1992 and the Minister for Roads and Traffic at the
Department of Transport from May 1992 - May 1993. He is on the Council of the
Royal Horticultural Society. He retired as an MP at the
1997 general election. His successor as Conservative candidate in Lincoln lost the seat to Labour's
Gillian Merron by over 11,000 votes. New boundaries introduced for the election contributed to this defeat, as it was projected that had Lincoln been fought on these boundaries in
1992, it would have had a Labour majority of about 1,000 (whereas Carlisle had won by just over 2,000 votes on the old boundaries). ==Farming==
