Question to the Department for Exiting the European Union :

To ask Her Majesty's Government whether they plan to negotiate with the EU an offer to UK citizens living outside of Northern Ireland but in Great Britain the opportunity to become EU citizens.

EU treaty provisions make clear that only citizens of EU Member States are able to hold EU citizenship. Therefore, when the UK ceases to be a member of the European Union, British nationals will no longer hold EU citizenship, unless they hold dual nationality with another EU Member State.
