I'm looking for a full sortable list of the results, for every constituency, ideally with as much information as possible: Turnout, # eligible voters, votes for each candidate (both # and %), winning majority (both # and %), etc.
The offical results are published by the Electoral Commission, on their web site https://www.electoralcommission.org.uk/our-work/our-research/electoral-data. The data for the 2017 June General election is not yet available (as of June 10th)
It includes "data on electorate sizes, turnout, rejected ballots and postal votes." as well as the number of ballots cast for each candidate.
