1945 Combined Scottish Universities by-election

The 1945 Combined Scottish Universities by-election was a by-election held from 9 to 13 April 1945 for the Combined Scottish Universities, a university constituency of the British House of Commons.

Vacancy
The seat had become vacant on 6 March 1945 when the National Liberal Member of Parliament (MP) George Morrison had resigned by the procedural device of accepting the post of Crown Steward and Bailiff of the Manor of Northstead, a notional 'office of profit under the crown' which is used as a procedural device to enable MPs to resign from the Commons.

Candidates
Two candidates contested the by-election. The Rector of the University of Glasgow, Sir John Boyd Orr, stood as an independent. He was a doctor and biologist, and founder of the Rowett Research Institute.

The other candidate was R. M. Munro of the National Liberal Party.

Result
The result was a victory for Boyd Orr, who won over 70% of the votes. He held the seat until 1946, when he resigned to take up the post of Director of the United Nations Food and Agriculture Organization.
