since 1983. Following the boundary review for the 2005 general election, Labour held a clear majority of 12% over the Conservatives, according to calculations of notional results (an estimate of how the seat would have voted if it had existed at the previous election) and the seat was 96th on the Conservatives' target list. The Liberal Democrats finished in a close third place at the election. However, former Conservative MSP David Mundell was successful in gaining the seat from Labour, with a swing of 8.0%. This left him as the sole Conservative MP representing a Scottish constituency at the 2005 general election, after the Conservative MP for Galloway and Upper Nithsdale, Peter Duncan was defeated when standing at the new Dumfries and Galloway constituency, and Conservative attempts to gain Angus from the SNP ended in failure. In 2010, Mundell was re-elected, with an increased majority. In 2015, after the SNP landslide victory in Scotland, he narrowly defeated the SNP candidate, Emma Harper by 798 votes, and was the only Scottish Conservative MP elected. However, following the SNP's losses at the 2017 snap general election, the Conservatives gained 12 seats in Scotland, with Mundell increasing his majority to 9,441 votes. Mundell was re-elected at the 2019 general election, but with a reduced majority, in an election where the SNP made gains across Scotland at the expense of Labour and the Conservatives.
