Merthyr Tydfil by-election, 1972

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.

NB: If one combines the totals for Labour and Independent Labour from the 1970 election the total was 80.59% making a loss of 32.01% of the vote.
