Banff and Buchan is a constituency of the House of Commons, located in the north-east of Scotland within the Aberdeenshire council area. It elects one Member of Parliament at least once every five years using the first-past-the-post system of voting.
The seat has been held by David Duguid of the Scottish Conservatives since 2017; until then the Scottish National Party had held the seat since 1987, with the then First Minister of ScotlandAlex Salmond representing the seat until 2010. In 2010, Eilidh Whiteford succeeded Salmond as the MP for Banff and Buchan, but the SNP vote share fell below 50% for the first time since 1992, due to a strong challenge by the Conservative Party. In the 2015 general election, the SNP achieved its best-ever result in the constituency, with Whiteford winning a 60.2% share of the vote and increasing her majority by more than 10,300 votes. In 2017, the constituency saw the second-largest swing to the Conservatives in all of Scotland (20.2%), bested only by the swing Colin Clark of the Conservatives achieved in defeating Alex Salmond in the neighbouring seat of Gordon (20.4%). At the 2019 general election, Banff and Buchan’s Conservative vote share bucked the Scottish trend and increased by 2.1%, increasing Duguid’s majority to over 4,000 votes and taking over 50% of the vote share.
The Aberdeenshire council area as a whole voted against Scottish independence in 2014.
In the 2017 general election there was a large swing from the SNP to the Conservatives, which observers attributed to anger at the SNP’s opposition to Brexit and support for a second independence referendum. After the election, The Guardian reported that, “In the coastal town of Peterhead, locals at the Waverley hotel were toasting Salmond’s first defeat since being elected as an MP in 1987. Murdo MacKenzie, 51, a former fisherman, said there was a lot of anger about Sturgeon’s stance on Europe. ‘Europe is dictating our fishing quotas. I’ve voted SNP all my life but if you take the power away from Westminster and hand it to Brussels, how is that independence?'”
