Chris Davies Conservative Jane Dodds Liberal Democrats A by-election was held in the UK Parliament constituency of Brecon and Radnorshire (Welsh: Brycheiniog a Sir Faesyfed) on 1 August 2019 after Chris Davies, who had held the seat for the Conservatives since the 2015 general election, was unseated by a recall petition.

Richard Livsey, a Liberal standing for the SDP–Liberal Alliance, won the seat in the 1985 Brecon and Radnor by-election and retained it in 1987.

[9] After receiving notice from the sentencing court, the Speaker of the House of Commons indicated on 24 April 2019 that he would be instructing the constituency's petition officer to begin the recall process.

The result reduced the working majority of the government (including confidence and supply from the DUP) in the House of Commons to one.

[1] The Brexit Party candidate was retired police chief superintendent Des Parkinson,[23] who previously stood in Montgomeryshire as a UK Independence Party (UKIP) candidate for election to the UK parliament in May 2015, to the Welsh Assembly in May 2016,[24] and as Dyfed-Powys Police and Crime Commissioner, also in May 2016.

[25] Dodds, the Liberal Democrat candidate, was also supported by Plaid Cymru, the Greens, Change UK and the Renew Party.

[3] Change UK called for an independent joint Remain candidate in a letter to the Liberal Democrats, Plaid and the Greens.

[30] Shortly after the result of the recall petition was announced, bookmakers made the Liberal Democrats odds-on favourites to win.

[3] In the final week before the election, Heidi Allen MP, former leader of Change UK and now sitting with The Independents, came to the constituency to campaign for Dodds.

Gill dismissed the idea due to Davies' support for the Withdrawal Agreement negotiated by Theresa May's government.

[39] In her victory speech, Jane Dodds said she would urge Prime Minister Boris Johnson to "stop playing with the future of our communities and rule out a no-deal Brexit".
