Kinross and Western Perthshire (UK Parliament constituency)

Kinross and Western Perthshire was a county constituency of the House of Commons of the Parliament of the United Kingdom from 1918 until 1983, representing, at any one time, a seat for one Member of Parliament (MP), elected by the first past the post system of election.

Constituency boundaries were defined in terms of the Representation of the People (Scotland) Act 1832 and the Redistribution of Seats Act 1885[2] and, by these terms, five detached parishes of the county of Perth and one detached parish of the county of Stirling were within the Clackmannanshire and Kinross-shire constituency.

[2] Also, by 1918, for local government purposes, under legislation dating from 1889, county boundaries throughout most of Scotland had been redrawn, and detached parishes had become generally historic.

The Representation of the People Act 1918 took account of new local government boundaries in definitions of new constituency boundaries, and the Kinross and Western Perthshire constituency was defined as covering the county of Kinross and the Central, Highland and Western districts of the county of Perth, including the county of Perth burghs of Aberfeldy, Auchterarder, Callander, Crieff, Doune and Dunblane.

This also applied to the by-election of late 1963, when newly elected prime minister Sir Alec Douglas-Home won the seat after renouncing his peerage in order to rejoin the House of Commons.
