Boundary changes which came into force in 2005 brought in many voters from more suburban areas formerly in the Angus constituency. Although estimates of the 2001 general election result on the new boundaries showed Labour ahead, the lead was exceptionally narrow, and after the SNP won the Scottish Parliament seat on the original boundaries in 2003, a close fight was expected (and occurred) in the 2005 general election. The constituency was gained by the SNP's Stewart Hosie, who won the constituency with a 1.0% vote majority ahead of Labour in 2005, which he increased to 4.5% at the 2010 general election.
