1991 Kincardine and Deeside by-election

The Kincardine and Deeside by-election was a parliamentary election held in Kincardine and Deeside, Scotland, on 7 November 1991, caused by the death of the Conservative Member of Parliament, Alick Buchanan-Smith on 29 August 1991.

The result was a gain for the Lib Dems from the Scottish Conservatives, with future party leader Nicol Stephen elected as the new Liberal Democrat Member of Parliament. Stephen held the seat until the 1992 general election, when it was regained by the Conservative Party. The SNP candidate Allan Macartney went on to be elected as the MEP for North East Scotland (European Parliament constituency) at the 1994 European Parliament election; a position he retained until his death in 1998. The Scottish Labour candidate, Malcolm Savidge, who finished in fourth place at this by-election, went on to be elected as the MP for Aberdeen North at the 1997 general election. Nicol Stephen was elected as Member of the Scottish Parliament for Aberdeen South in 1999 and became Leader of the Scottish Liberal Democrats in 2005.

It was held on the same day as the by-election in Langbaurgh, which saw another Conservative defeat.
