2019 UK General Election Candidates' and Incumbents' Positions in the UK's Referendum on Membership of the European Union, 2019-2020

The data provide details of the positions taken in the UK's 2016 referendum on EU membership by (a) Conservative and Labour MPs elected at the 2019 general election and (b) Conservative and Labour candidates standing in English and Welsh constituencies at the 2019 general election. These data were sourced from statements made by MPs on their websites or on their Twitter or Facebook pages. Details of the source of each candidate's position are included in the data. The data on MPs also include the year they were first elected. There is a small number of cases in which MPs did not disclose the positions on the UK's referendum on EU membership and these are noted in the data. The proportions of candidates who did not disclose their position is higher and, again, this is noted in the data as appropriate. The data allow for descriptions of the level of division within the Conservative and Labour parliamentary parties as well as among their candidates, and provide an independent variable that could be used in studies where a politician's referendum position is believed to affect other things.
