The constituency name refers to the former county of Montgomeryshire and the former district of Glyndŵr. Upon its abolition, the predecessor seat, Montgomeryshire, was the only one in Wales never to elect a member of the Labour Party. At the 2024 election Montgomeryshire and Glyndŵr elected Steve Witherden, the first Labour MP ever to represent the Montgomeryshire area in the House of Commons, meaning that the party has now won in every area of Wales in their history.
Boundaries
The constituency comprises the following areas:[2][3]
From Wrexham County Borough: Cefn, Dyffryn Ceiriog/Ceiriog Valley, Chirk North, Chirk South, Esclusham, Johnstown, Pant, Penycae, Penycae and Ruabon South, Plas Madoc, Ponciau, and Ruabon.
The official spelling of the constituency, in English and Welsh, uses the spelling 'Glyndŵr' with a circumflex over the "w".[4]
On 25 June the Conservative Party withdrew support for their candidate due to the 2024 United Kingdom general election betting scandal.[6] It was confirmed on behalf of the returning officer that his name and party designation had to remain on the ballot paper, as the suspension came after nominations for the election had closed.[7][8] On 20 June a YouGov poll had predicted Montgomeryshire and Glyndŵr would be the only seat in Wales to be won by the Conservatives, by a narrow margin.[9]
