Parliamentary constituency in the United Kingdom, 1950–1983
The Perth and East Perthshire constituency was defined as covering the burghs of Abernethy, Alyth, Blairgowrie, Coupar Angus, Perth, and Rattray in the county of Perth and the Blairgowrie, and Perth districts of the county.
For the February 1974 general election, the results of the Second Periodical Review of the Boundary Commission were implemented, and there was a minor change to the boundaries of Perth and East Perthshire. It was redefined as covering the burghs of Abernethy, Alyth, Blairgowrie and Rattray (now a single burgh), Coupar Angus, and Perth in the county of Perth, and the Eastern, and Perth districts of the county.
February 1974 boundaries were used also in the general elections of October 1974 and 1979.
