U.K. Prime Minister Boris Johnson has told European Council President Donald Tusk that he will send a letter to the EU requesting an extension of the 31st October Brexit deadline on Saturday night, an EU official said after the pair spoke by phone.

On Twitter, Tusk wrote that he “just talked to Boris Johnson about the situation after the vote in the House of Commons.”

A defiant Boris Johnson said he would not negotiate a further delay to Britain’s departure from the European Union after parliament voted on Saturday to postpone a vote on his Brexit deal.

Parliament voted 322 to 306 in favour of an amendment put forward by Oliver Letwin, a former Conservative cabinet minister.

According to legislation passed earlier, the vote means Johnson is obliged to write to the European Union seeking a delay beyond Britain’s scheduled departure date of October 31.

However, Johnson has repeatedly vowed he will not do this and on Saturday he stuck to that line.
