The below Parliamentary question was asked by Christopher Chope on 2016-02-02.
To ask the Minister for the Cabinet Office, how many UK citizens resident overseas registered to vote in the 2015 general election; and how many such citizens voted in that election.
105,845 overseas electors were registered to vote in May 2015. The marked register, which records electors who have cast their vote, is not collated centrally. It is therefore not possible to tell how many overseas electors voted at the 2015 General Election.
