Monmouthshire was won by Labour at the 2024 general election, with a majority of 3,338 votes over Conservative. This page covers every general election in Monmouthshire from 1832 to 2024.
This constituency elected more than one MP at once in some years. Before the Redistribution of Seats Act 1885 (and in a shrinking number of boroughs through 1948), most UK constituencies elected two or more MPs together by "multi-member plurality" (block vote): each elector could cast one vote per available seat, and the top vote-getters overall were all elected. In those elections below, "Elected" lists every MP returned, "Votes" is the count that secured the last seat, and "Majority" is the gap between that seat and the first candidate who missed out.
