Editing Perthshire (section)

===1918–1975===
In 1918 there was a further redistribution. Perthshire was combined with [[Kinross-shire]] to form a parliamentary county, divided into two constituencies:

*[[Perth (UK Parliament constituency)|Perth]] constituency consisted of the burgh of Perth, the former Eastern constituency and part of the Western constituency. In 1950 it was renamed Perth and East Perthshire. The area included in the constituency was defined in 1948 and 1970 as the burghs of Perth, Abernethy, Alyth, Blairgowrie and Rattray and Coupar Angus; and the Eastern and Perth districts of the county of Perth.<ref name="PCorder">The Parliamentary Constituencies (Scotland) Order 1970 (S.I. 1970 No. 1680)</ref>
*[[Kinross and Western Perthshire (UK Parliament constituency)|Kinross and Western Perthshire]]: the constituency consisted of the entire County of Kinross, the burghs of Aberfeldy, Auchterarder, Callander, Crieff, Doune, Dunblane and Pitlochry; and the Central, Highland and Western districts of the county of Perth.<ref name="PCorder"/>

These boundaries continued in use until 1983, when new constituencies were formed based on the Local Government regions and districts created in 1975.
