1930 East Renfrewshire by-election
The seat had become vacant on when the constituency's Unionist Member of Parliament (MP), Alexander Munro MacRobert, had died on 18 October 1930, aged 57. He had been East Renfrewshire's MP since winning the seat from Labour at the 1924 general election.
On a slightly-reduced turnout, the result was a victory for The Marquess of Clydesdale, who won 52% of the votes. He was re-elected at the next two general elections, remaining East Renfrewshire's MP until he succeeded to the Dukedom in 1940, triggering another by-election.
