The European Parliament has told Theresa May to 'indicate the way forward' at today's EU summit - and suggests announcing a referendum, a general election or a revocation of Article 50.

The Prime Minister is set to attend the EU27 summit in Brussels, while member states make a decision on her plea to extend Article 50.

All 27 heads of government must agree to the extension, or else the UK will fall into the default position of a no-deal Brexit on Friday.

Ahead of the summit, the Conference of Presidents and the Brexit Steering Group of the European Parliament called on Ms May to clearly layout her Brexit plan.

They say they believe a no-deal exit would be 'detrimental' to both citizens and the economy, and should be avoided.

But in order to steer clear of this scenario, they say it's up to the Prime Minister to indicate the way forward.

A statement reads: "We believe that when Prime Minister May comes to the European Council today she cannot come empty handed.

Read the European Parliament's statement in full.

"We expect the Prime Minister to indicate what are the prospects of the cross-party talks between the Government and the Labour Party and their anticipated results and whether a solid parliamentary majority in support of such an agreement exists.

"If not, she should indicate clearly the way forward (be it a referendum, a general election, or a revocation)."

Although the possibility of an extension is on the cards, the European Parliament have made clear that a delay does not equate to reopening the Withdrawal Agreement, or initiating negotiations on future relations.

They also went on to say that in the case of a longer extension, the UK will be obligated to participate in EU elections.
