Theresa May has been accused of back-peddling on greater scrutiny for her Brexit plans, after refusing to say that the House of Commons will be allowed a vote on Britain's European Union withdrawal.
In a speech stressing Europe's red lines in Brexit negotiations due to start before April, Tusk said British Prime Minister Theresa May has signaled a "de facto will to radically loosen relations with the EU" by pledging to give priority to regaining United Kingdom sovereignty over immigration.
They have called a debate in Parliament on Wednesday on an opposition motion calling for lawmakers "properly to scrutinize" Britain's position.
May has said Britain would invoke Article 50 of the Lisbon Treaty by the end of March, which would launch a two-year process resulting in the country's exit from the 28-nation bloc by summer 2019.
"It's frankly astonishing that the government proposes to devise the negotiating terms of our exit from the European Union, then to negotiate, and then to reach a deal without a vote in this house", he said. May however, stated that Brexit talks must respect decision of British people and that there shouldn't be an attempt to block Brexit or undermine the negotiating position of the government. Labour Brexit spokesman Keir Starmer said.
"The idea that parliament somehow wasn't going to be able to discuss, debate, question. was frankly completely wrong", she said, noting that MPs would have "every opportunity to debate" her government's ideas.
Those fears - that Britain will give up full access to the EU's single market - pushed sterling to 31-year lows last week, including on Friday when it lost 10 percent within minutes.
"We are listening to the British people and delivering on that [referendum] result", she said. "The question is what is the agenda for that process and that needs to be held to account in Parliament now and that means it needs to be open to a vote". There is no mandate for the terms.
"There will not be a vote on triggering Article 50".
The government's amendment promising lawmakers a voice, if not a vote, on Brexit terms helped secure support for Labour's motion, which passed unopposed.
She said "we should be holding our heads in shame" that Nottingham University, which is close to her constituency, was struggling to retain and recruit global academics because they no longer felt welcome in the UK.
"It's frankly astonishing that the government proposes to devise the negotiating terms of our exit from the European Union, then to negotiate and then to reach a deal without a vote in this house".
"[A government] that has no strategy for negotiating Brexit and offers no clarity, no transparency and no chance of scrutiny of the process for developing a strategy".
