Question to the Cabinet Office:

To ask Her Majesty's Government what was the total number of eligible electors on the register, resident outside the UK, for the June 2017 General Election; and what proportion of them voted.

The Government does not hold central records of the total number of eligible electors on the register who reside outside of the UK, where overseas they reside, and the proportion of them who voted.

The Electoral Commission has produced reports into the administration of the 2017 and 2015 General Election and the 2016 EU referendum. The reports contain information on the number of overseas electors but does not state where they reside.
