British Prime Minister Theresa May on Friday issued the European Union (EU) with an ultimatum to come up with an alternative plan for Brexit and treat the UK with respect in the negotiations.
Her televised statement from Downing Street came after a day of upheavals in Salzburg at Austria, during which European Council Head Donald Tusk announced that the UK's Brexit plans were unworkable.
May hit back at the EU leaders for rejecting her plan with no alternative at this "late stage of negotiations", saying it was "not acceptable".
"I will not overturn the result of the referendum nor will I break up my country," a defiant British PM said.
"Yesterday Donald Tusk said our proposals would undermine the single market. He didn't explain how in any detail or make any counter-proposal. So we are at an impasse," she said.
Her statement further noted: "Throughout this process I have treated the EU with nothing but respect. The UK expects the same, a good relationship at the end of this process depends on it.
"At this late stage in the negotiations, it is not acceptable to simply reject the other side's proposals without a detailed explanation and counter proposals. So we now need to hear from the EU what the real issues are and what their alternative is so we can discuss them. Until we do, we cannot make progress."
May said the first option would "make a mockery of the referendum", while the second would mean Northern Ireland would be "permanently separated economically from the rest of the UK by a border down the Irish Sea."
