Prime Minister Theresa May warned on Friday that Brexit talks are "at an impasse" and the UK must step up its preparations for leaving the EU without a deal.

In a dramatic statement in Downing Street, May accused the EU of failing to show Britain "respect" in negotiations. This followed a day in which EU leaders publicly humiliated the prime minister at a summit in Salzburg.

Adding that the UK would not accept any Brexit deal that risked the break-up of the United Kingdom, May said, "'We must and will prepare ourselves for no deal."

She added: "No one wants a good deal more than me, but the EU should be clear: I will not overturn the result of the referendum. Nor will I break up my country."
