THERESA MAY faced yet another Brexit headache today as the DUP took aim at her “slapdash” approach after she begged European Council President Donald Tusk for a delay until June 30.

Prime Minister Ms May stated that she wanted the option for Britain to leave the EU before that date if her Withdrawal Agreement was ratified sooner.

Article 50 has already been extended from the end of March to April 12 as a result of her repeated failure to get MPs behind her deal.

Ms May has now said that she will seek to get her deal approved by the Commons before European Parliament elections on May 23.

Arlene Foster, leader of the DUP — which props up Ms May’s minority government — said that the request for an extension was “unsurprising but unsatisfactory” and reflected the “chaotic” nature of the PM’s negotiations with the EU.

Ms May’s request will be considered at an emergency EU summit on April 10, where it requires the unanimous agreement of the leaders of the remaining 27 member states.

But EU sources said Mr Tusk is recommending a longer postponement of one year, with a break clause in the case of earlier ratification, in a so-called “flextension” deal.

Labour leader Jeremy Corbyn and Ms May are in ongoing talks to find a “single unified approach” that could command the support of MPs and break the Brexit deadlock.

Speaking during a visit to south Wales to mark Labour’s victory in the Newport West by-election, Mr Corbyn said: “There’s been no obvious move on the side of the government as of yet, we’re continuing those talks.

“Our position is there has to be a market relationship with Europe, there has to be a customs union, and we have to be able to develop our own policies when we’re in government, particularly competitions policy which I’m concerned about.”

Mr Corbyn said the prospect of a second referendum would be “in the mix, in the discussion, in the debate, which I assume will be next week.”

But he added that only the government will know if it will be debated or not.
