The Roxburgh and Berwickshire 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, Scottish Westminster constituencies were mostly replaced with new constituencies.[1]
Following its First Periodic review of constituencies to the Scottish Parliament, the Boundary Commission for Scotland recommended that the Roxburgh and Berwickshire seat be expanded to form the newly shaped Ettrick, Roxburgh and Berwickshire constituency in time for the 2011 election.
