EU Referendum Act
The European Union Referendum Act (the Act) received Royal Assent on 17 December 2015 and was brought into force on Monday 1 February 2016.
The Act made additions and amendments to the framework set out in PPERA to establish a regulatory framework for a referendum on the UK's membership of the EU.
Designating lead campaigners
A designated lead campaigner is the lead campaign group for one side of the debate. It acts as the lead campaign group on behalf of those campaigning for that outcome.
On 13 April 2016, we designated The In Campaign Ltd as the lead campaigner for the remain outcome and Vote Leave Ltd as the lead campaigner for the Leave outcome at the referendum on the UK’s membership of the European Union.
We carried out an assessment of the referendum question, to make sure that it is clear and easy for voters to understand.
