In the Parliamentary Constituencies Order 2023, the name is given as Caerfyrddin (Carmarthen).[2] Of the twenty-five Welsh constituencies with names in both English and Welsh, Caerfyrddin is the only one where the Welsh name comes first followed by the English name in brackets (in each of the other cases, the opposite is true). Caerfyrddin is the form used by the UK Parliament.[3]
Because the seat contained mining areas in the valley of the River Gwendraeth (until the 1980s), much countryside and a high proportion of Welsh speakers, it was fertile territory for the Labour Party, the Conservatives and Plaid Cymru alike. Although the Conservatives never won the seat, they came within 1200 votes of doing so in 1983.
Carmarthen is notable as the first constituency to elect a Plaid Cymru MP, Gwynfor Evans, at a 1966 by-election. Evans was later involved in one of the closest General Election results ever in February 1974, when he lost to the Labour candidate by only three votes.[4][5] The constituency also shot to fame in the following election in October 1974 as the only seat in the country to see its turnout rise on that of February 1974.
^The BBC article quoted above says that it was the second closest General Election result since the Second World War. But the Winchester general election result of 1997 was closer.
