West Scotland is one of the eight electoral regions of the Scottish Parliament. Ten of the parliament's 73 first past the post constituencies are sub-divisions of the region and it elects seven of the 56 additional-member Members of the Scottish Parliament (MSPs). Thus it elects a total of 17 MSPs. The West Scotland electoral region was created as a result of the First Periodic Review of Scottish Parliament Boundaries and largely replaced the West of Scotland region.
