The European Union has claimed Brussels "never intervenes in referendums" after being told to keep its nose out of Iceland's Brexit-style vote later this month. Polling suggests the vote remains on a knife-edge, with a recent Maskina survey suggesting 44 per cent would vote in favour of accession to the EU and 39 per cent would vote against. Iceland would still likely need to hold a second vote on joining the EU if voters decide to proceed with negotiations. Brussels' then-Brexit negotiator Michel Barnier held direct meetings with figures pushing for a second referendum on EU membership, including Sir Sadiq Khan in October 2018. Despite Danish voters rejecting the 1992 Maastricht Treaty, the EU forced another vote on the matter the following year.
