All three devolved first ministers have now written to the Prime Minister seeking to ensure that the referendum on the UK’s EU membership is not held in June. The current thinking suggests that 23 June may be in David Cameron’s mind, assuming all goes well in reaching a final agreement with the other member states in the renegotiation. The First Ministers’ concern is proximity to devolved elections, and they are right to be concerned; the surprise is that their concern is not shared by Conservatives, or Labour, at Westminster.
The timetable for the EU referendum is not clear, but there are two fixed dates running up to the process. The first is the deadline for publication by the UK Government of
a report which contains … information about rights, and obligations, that arise … as a result of the United Kingdom’s membership of the European Union, and … examples of countries that do not have membership of the European Union but do have other arrangements with the European Union (describing, in the case of each country given as an example, those arrangements).
This is required by section 7 of the European Union Referendum Act 2015, and must take place not less than 10 weeks before the referendum date.
The second is the formal referendum campaign period, during which the two designated In and Out campaigns will have referendum election broadcasts, rights to public funding, and be required to keep detailed accounts. All that is complicated and requires effort and engagement from those involved in campaigning (and can easily be got wrong). It also means engaging the public with issues about the UK’s future relationship with Europe rather than parties’ plans for taxation, housing policy or the health service. That period starts 10 weeks before referendum polling day.
