The results of the Third Periodical Review of the Boundary Commission for Scotland were implemented for the 1983 general election of the House of Commons of the Parliament of the United Kingdom (Westminster). The review defined 30 burgh constituencies (BCs) and 42 county constituencies (CCs), with each electing one Member of Parliament (MP) by the first past the post system of election. Therefore, Scotland had 72 parliamentary seats. 1983 boundaries were used also in the general elections of 1987 and 1992. The results of the Fourth Periodical Review were implemented for the 1997 general election
