Question to the Cabinet Office:

To ask the Chancellor of the Duchy of Lancaster and Minister for the Cabinet Office, whether (a) his Department and (b) the Electoral Commission has made an estimate of (i) the number of EU nationals over the age of 18 living in the UK in each constituency and (ii) the cost of enabling them to vote in a General Election.

Figures on the number of individual electors and their characteristics are not held centrally. Such data are held by individual Electoral Registration Officers (EROs).

In line with its statutory duty, the Electoral Commission have published a report into the administration of the European Parliamentary Election earlier this year. As part of this publication, the Electoral Commission included figures on the number of citizens of other EU Member States on the electoral registers as of 23 May 2019.

The report is available here; the relevant section is entitled "Impact on EU citizens: How many EU citizens were included in the register":

EU citizens cannot vote in Parliamentary general elections. Citizenship restrictions are the norm for participation in national elections in the EU. There is no requirement in EU law to permit non-national EU citizens to vote in national elections and, so far as we are aware, no other EU Member State (other than Ireland) does so.
