The Banff and Buchan constituency was created at the same time as the Scottish Parliament, in 1999, with the name and boundaries of an existing Westminster constituency. In 2005, however, the boundaries of the Westminster (House of Commons) constituency were subject to some alteration.
Following the First Periodic review of constituencies for the Scottish Parliament, Banff and Buchan has become the newly drawn seat of Banffshire and Buchan Coast for the elections in 2011.
Council area
The Holyrood constituency covered a northern portion of the Aberdeenshire council area. The rest of the Aberdeenshire area is covered by two other constituencies, both also in the North East Scotland electoral region: Gordon was the constituency to the south of the Banff and Buchan constituency, and the former West Aberdeenshire and Kincardine was further south. Gordon also covered a small eastern portion of the Moray council area.
