MEPs are set to adopt a resolution on Tuesday (28 June) urging Britain to end the ”damaging uncertainty” of Brexit by quickly starting exit talks.

European Parliament (EP) members earlier roared criticism at David Cameron when the British prime minister announced that he would hand over responsibility for the UK’s exit procedure to a successor in October.

Leaders of four political groups in the EU assembly – the centre-right EPP, the socialists, liberals, and greens – drafted a resolution over the weekend in which they call upon the UK to immediately activate article 50 of the EU treaty.

The clause says that a member state needs to officially notify the EU Council that it intends to withdraw from the Union, triggering exit talks.

The EP’s draft text, to be adopted at an extraordinary session ahead of the EU summit on Tuesday, warns of the ”damaging uncertainty for everyone” if the UK postpones the negotiations.

If the draft were to be adopted in its current form, it would see the EP throw its weight behind European Commission president Jean-Claude Juncker and several other EU leaders who have called for a swift divorce.

But it’s unsure whether MEPs will stick to their hard line.
