May said that if she could not agree a unified approach with Labour leader Jeremy Corbyn then the government would agree a number of options on the future relationship with the EU
Prime Minister Theresa May said on Tuesday she would ask the European Union for a further delay to Brexit beyond 12 April to give her time to sit down with the opposition Labour Party in a bid to break the impasse over Britain's departure.
Nearly three years since the United Kingdom voted to leave the EU in a shock referendum result, British politics is in crisis and it is unclear how, when or if it will ever leave the European club it first joined in 1973.
In a hastily arranged statement from her Downing Street office after spending more then seven hours chairing crisis cabinet meetings on how to plot a way out of the Brexit maze, May said she was seeking a further extension to Brexit.
"We will need a further extension of Article 50, one that is as short as possible and which ends when we pass a deal. And we need to be clear what such an extension is for, to ensure we leave in a timely and orderly way," she said.
"I am offering to sit down with the leader of the opposition and to try to agree a plan that we would both stick to ensure that we leave the European Union and that we do so with a deal."
The pound rallied against the dollar as much as 0.3% to above $1.31. It also strengthened against the euro to 85.43 pence.
May said that if she could not agree a unified approach with Labour leader Jeremy Corbyn then the government would agree a number of options on the future relationship with the EU and put them before the House of Commons in a series of votes.
The government, she said, would then abide by the decision of the House of Commons.
