Candidate selection process

Each party had its own selection process. The processes used by Labour and the Conservatives were described by PoliticsHome as "secretive" and "controversial".

In June 2022, former Channel 4 journalist Michael Crick launched a Twitter account called Tomorrow's MPs, documenting the selection process of parties candidates in the runup to the next general election.

Conservative On 5 April 2023, Home Secretary and Fareham MP Suella Braverman defeated Meon Valley MP Flick Drummond by a majority of local party members of 77 to 54, to be preselected for the new seat of Fareham and Waterlooville. Drummond later won the contest to be selected for Winchester, a seat far more likely to be gained by the Liberal Democrats.

On 17 April 2023, Chairman of the Conservative Party Greg Hands announced the first 19 seats that would open selections. The seats were listed by ConservativeHome as Bicester and Woodstock, Calder Valley, Camborne and Redruth, Canterbury, Coventry South, Earley and Woodley, Eltham and Chislehurst, Hazel Grove, Hove and Portslade, Isle of Wight East, Kingston upon Hull West and Hessle, Milton Keynes South, Norwich North, Selby, South Cambridgeshire, South West Devon, Tamworth, West Bromwich and West Lancashire.

On 29 May, the Conservative Campaign Headquarters announced the next 24 seats that would open selections: Altrincham and Sale West, Bishop Auckland, Bromsgrove, Broxbourne, Chippenham, Coventry North West, Eastleigh, Esher and Walton, Exeter East and Exmouth, Halifax, Hendon, Henley, Mid Bedfordshire, Newport West and Islwyn, Norwich South, Reigate, Rugby, Scarborough and Whitby, South Shropshire, Stevenage, Stoke-on-Trent Central, Walsall and Bloxwich, West Suffolk and Wolverhampton West.

On 2 June 2023, Bromsgrove Conservatives began their selection process for a candidate.

On 12 June, Boris Johnson resigned as an MP, triggering a by-election. The same day, Nigel Adams also resigned as an MP. On 19 June, David Warburton gave up his seat in Parliament.

On 11 August, the Conservatives opened selections for 26 seats: Alyn and Deeside, Bridlington and The Wolds, Bristol North West, Bury South, Clwyd North, Colchester, Crawley, Croydon East, Doncaster North, Dorking and Horley, Frome and East Somerset, Glastonbury and Somerton, Heywood and Middleton North, Huntingdon, Leeds East, Leeds West and Pudsey, Mid Cheshire, North West Leicestershire, Pontefract, Castleford and Knottingley, Richmond Park, Sittingbourne and Sheppey, Southampton Itchen, St Albans, Wakefield and Rothwell, Waveney Valley and Wirral West.

Nadine Dorries announced her intentions to resign and officially resigned on 29 August. Chris Pincher left Parliament on 7 September.

On 22 September, nominations opened in 10 seats: Bath, Bolton South and Walkden, Bridgend, Coventry South, Lancaster and Wyre, Norwich North, Telford, West Bromwich, Westmorland and Lonsdale and Wimbledon.

On 30 September 2023, The Telegraph reported that the Conservatives had only selected 65 candidates out of their target of 100 before the Conservative Party Conference.

On 13 October 2023, nominations opened in 18 seats: Bristol North East, Cardiff North, Cardiff West, Chester North and Neston, City of Durham, Croydon West, Dwyfor Meirionnydd, Gower, Hampstead and Highgate, Harrow West, Leicester East, Mid Cheshire, Nottingham East, Oxford West and Abingdon, Queens Park and Maida Vale, Wirral West, Wolverhampton South East and Wolverhampton West.

On 23 November 2023, Nick Rose, who had been the candidate for Norwich North, resigned.

In late 2023, two candidates were removed after MI5 warned in 2021 that they were potential Chinese spies. In April 2024, the selection process was internally criticised by party members for "purging Brexit-backing candidates". The preferred selection of One Nation Conservatives by the party leadership over right-wing candidates was reported on. This included the former Deputy Leader of the UK Independence Party and Conservative MEP David Campbell Bannerman who was blocked in South Norfolk.

On 28 May 2024, it was reported that the Conservatives had 183 candidates to select.

On 28 May 2024, presenter Iain Dale announced that he would be stepping back from his LBC radio show to run as a Conservative candidate in the election, hoping to stand in the seat of Tunbridge Wells, where he lives. However on 31 May he announced that he had decided not to put his name on the shortlist after comments he had made about Tunbridge Wells, two years earlier, emerged online. In the clip he had said that he didn't like living in the town he was running in. Dale defended himself by stating that "there is a context to it, but nobody's interested in context or nuance in these situations".

By 7 June, the Conservatives had filled all seats with candidates in Great Britain except for Rotherham. Laila Cunningham was originally selected as the Conservative candidate for the seat, but withdrew shortly before the nominations deadline. As the party did not field a replacement, it is the only seat in Great Britain aside from the Speaker's seat of Chorley in which no Conservative candidate was nominated.

Labour In March 2021, the local parties in East Ham and West Ham were suspended following allegations of electoral fraud, disbanding the internal selections committee. This was a precursor to contentious selections across East London, between centrist supporters of Keir Starmer and Momentum-backed supporters of former leader Jeremy Corbyn.

The Labour Party selected many prospective parliamentary candidates throughout 2022.

In July 2022, a trigger ballot was held in Ilford South to determine whether MP Sam Tarry should face reselection; Tarry lost the vote by 57.5% to 42.5%. On 10 October 2022 a reselection vote was held, which Tarry lost to local council leader Jas Athwal by 361 votes to 499. In late 2022, councillor Dominic Beck stood down as Labour PPC for Rother Valley.

By 1 January 2023, a total of 77 Constituency Labour Parties had selected prospective parliamentary candidates.

In February 2023, BBC News reported that local Labour parties were being overruled over parliamentary selections by "a clique in London". Nine members of the selection committee in Bolton North East Parliamentary Labour Party resigned after the national party imposed a shortlist on them. The main contention was over the fact that Leigh Drennan, the chair of North West Labour, was not shortlisted despite being endorsed by Deputy Labour Leader Angela Rayner.

In March 2023, Labour's national executive committee resolved not to endorse Jeremy Corbyn for Islington North in the next general election, preventing him from seeking re-election as a Labour candidate. Labour later chose Praful Nargund as their candidate, which was shortly followed by Corbyn announcing his intention to run as an independent in the constituency.

On 23 May 2023, eleven members of the Copeland local Labour Party executive resigned following the decision of the National Executive Committee of the Labour Party not to longlist local councillor Joseph Ghayouba for selection. Local officials said it showed a "shameless disregard for democracy" by Labour's national ruling body. On 6 June 2023, former Copeland PPC Gillian Troughton withdrew from the selection in Whitehaven and Workington, describing the selection process as "frustrating and ultimately disenfranchising".

On 26 May 2023, the Wirral West Constituency Labour Party was suspended by the national party, following complaints. This was the same week that the local MP Margaret Greenwood announced that she was standing down at the next general election. As Wirral South was abolished, incumbent MP Alison McGovern challenged neighbouring MP Mick Whitley for the nomination in Birkenhead. Whitley was deselected on 16 June 2023.
