As a result of the first periodical review of Scottish Parliament (Holyrood) constituencies, new constituencies and additional member regions of the Scottish Parliament were introduced for the 2011 Scottish Parliament election. The D'Hondt method is used, as previously, in the allocation of additional member seats. The Boundary Commission for Scotland began the review as announced on 3 July 2007, and provisional proposals were published on Thursday 14 February 2008. The Orkney and Shetland constituencies were taken into account, however, in review of boundaries of the additional member regions.
