EU leaders have rejected Theresa May’s attempt to delay Brexit until June 30.

In a fresh snub for the Prime Minister, the EU Council summit in Brussels yesterday decided to approve her request for an Article 50 extension in principle – but were locked in discussions late last night over what length of time they would be prepared to grant.

A meeting to finalise the offer dragged on long after its scheduled conclusion, amid reports that the text was being torn up and rewritten.

As we went to press last night it appeared the EU had settled on a date of May 22 for the UK to leave under the terms of the Withdrawal Agreement – provided the Commons backs it as the PM hopes next week. This is five weeks short of the June 30 date requested by the Prime Minister and would present her with a race against time to complete legislation needed for an orderly UK withdrawal.

However, should MPs vote down May’s deal the EU were prepared to offer a different extension to avert an “accidental no deal” outcome, until April 11 – the very last moment the UK could decide to participate in European Parliament elections.

By then, the EU would expect the UK to have made up its mind on a Plan B. A softer Brexit, a no deal exit, a general election or a second referendum would all be among the options which presumably could yet be considered.

May made the case for a June 30 extension in a 90-minute presentation to the EU27, before leaving them to discuss their response in her absence.

The draft communique suggested that an extension could stretch beyond the May 23-26 European elections only if the UK takes part.

“Given that the UK does not intend to hold elections to the European Parliament, no extension is possible beyond that date,” said the draft.

The communique also suggested the EU would formally adopt two documents agreed by May with European Commission president Jean-Claude Juncker in Strasbourg last week, with the intention of reassuring MPs that the controversial backstop will not be permanent.

As she arrived in Brussels for what was slated to be the UK’s final EU summit as a member of the bloc, the Prime Minister said she “sincerely hopes” Britain will be able to leave with a deal.

But several leaders warned that if MPs turn down her Withdrawal Agreement for a third time, the UK could be heading for a no-deal Brexit.

Describing the UK as being in “political crisis”, Macron said: “There needs to be a profound political change if there is to be an extension which is anything other than technical.”

Luxembourg’s prime minister Xavier Bettel said: “At the moment, there are more non-options on the table than options ... I sometimes have the feeling that we are in the waiting room, a bit like Waiting for Godot. But Godot never came so I hope this time they will come.”

Italian PM Giuseppe Conte said: “We think a short delay could be useful. We need to wait for a new vote in the British Parliament.”

Jeremy Corbyn held what he described as “very constructive discussions” in Brussels with EU chief negotiator Michel Barnier and European Commission secretary general Martin Selmayr which he said had focused on the means to prevent a no-deal Brexit next Friday.

The Labour leader declined to rule out the option of halting Brexit by revoking the Article 50 letter informing Brussels of Britain’s intention to quit.

Asked if he was willing to consider revocation if it was the only way to prevent no-deal Brexit, he said: “These are hypotheticals.

“So far as we’re concerned, we think there’s an urgency in constructing a majority for an agreeable solution and that’s what we’re concentrating on at the moment.”
