1972 Merthyr Tydfil by-election
The Merthyr Tydfil by-election of 13 April 1972 was held after the death of S. O. Davies on 25 February the same year. The Labour Party won the by-election in what had traditionally been a safe seat, although Davies had been elected in the 1970 general election as an Independent after he had been deselected due to his age.Results
