Jeremy Corbyn, the sitting Labour leader, has been challenged by Owen Smith, the MP for Pontypridd. Now that both are on the ballot, constituency Labour parties (CLPs) can give supporting nominations. Although they have no direct consequence on the race, they provide an early indication of how the candidates are doing in the country at large. While CLP meetings are suspended for the duration of the contest, they can meet to plan campaign sessions, prepare for by-elections, and to issue supporting nominations.

Scottish local parties are organised around Holyrood constituencies, not Westminster constituencies. Some Westminster parties are amalgamated - where they have nominated as a bloc, we have counted them as their separate constituencies, with the exception of Northern Ireland, where Labour does not stand candidates. To avoid confusion, constitutencies with dual language names are listed in square [] brackets. If the constituency party nominated in last year's leadership race, that preference is indicated in italics. In addition, we have listed the endorsements of trade unions and other affliates alongside the candidates' names.
