1945 Monmouth by-election
# 1945 Monmouth by-election

The 1945 Monmouth by-election was a by-election held for the British House of Commons constituency of Monmouth in Wales on 31 October 1945. The seat had become vacant on the death of the sitting Conservative Member of Parliament (MP) Leslie Pym, and the by-election was won by the Conservative candidate Peter Thorneycroft.

## Vacancy

The Conservative MP Leslie Pym had died at the age of 61 on 17 July 1945, twelve days after polling in the 1945 general election, but nine days before the declaration. He was thus unusually declared elected posthumously. Pym had held the seat since a by-election in 1939.
