Theresa May was "The greatest giveaway of sovereignty in modern times", as she faced a potential devastating pincer movement from Tory retirees and leavers condemning her Brexit plans.
Boris Johnson, resigned from the government and called for a second referendum on Brexit, former education secretary Justine Greening launches an attack on the prime minister, saying her plans would leave the country in the "worst of all worlds".
Piling yet more pressure on May, Greening – who resigned from the cabinet in January – backed the former transport minister's call for another public vote and said MPs should reject the Prime Minister's deal. Greening told the Observer: "The parliamentary deadlock has been clear for some time. It's the biggest giveaway of sovereignty in modern times.
"Instead, the government and parliament must recognize we should give people a final say on Brexit. Only they can break the deadlock and choose from the practical options for Britain's future now on the table. "
Greening added: "Like many of us, Jo Johnson is a pragmatist on Britain's relationship with the EU. But Conservative MPs can no longer see this sovereignty giveaway from No 10 leaves our country with less than the rules that govern our lives … That's not the national interest, it's the worst of all worlds and it resolves nothing. "
Common cause, protesting that the blueprint would leave the UK tied to the EU's economic systems but with no say over the rules. As a result, they say they do not want to get back from Brussels, it would not do the reverse and leave the UK with less power.
A letter to the prime minister, organized by the standUp4Brexit campaign and circulated among Tory party constituency chairs, seen by the Observer, states that May's proposals represent a "significant blow to our sovereignty".
It says it would leave Britain "trapped in a customs union with the EU indefinitely," as the current plans could do, "fly in the face of the referendum result" and risk "deliver a Corbyn government at the next election" ,
The letter goes on: "As the Conservative Chairmen, and therefore the Lancaster House speech – namely, leaving the customs union, the single market and ECJ over-all. "
In his resignation statement on Friday, Jo Johnson said the country was "on the brink of the great crisis" since the second world was and argued that the Brexit deal on offer was not "anything like what was promised". He denounced the choice between May's plans or a no-deal outcome as a "failure of British statecraft on a scale beyond the Suez Crisis" that had left Britain facing "vassalage" or "chaos".
On Saturday, speaking on BBC Radio 4's Today programs, he went further, saying he would say he was going to make a difference. "This is an extraordinarily hopeless basis," he said ,
Asked whether he believed other ministers should quit over the issue, he / she asks them to do so. "I think this is so important that it's up to MPs to take a stand. I've done so, if others feel it's right for you to do so, good on them. "
One Tory donor last night that May be heading towards "explosion" with her own party. "She made incompatible promises to different constituencies," he said. "An explosion is now the best forecast."
Campaigners for a second referendum claim that support for another vote is growing. The pro-stay Best for Britain group said that for the first time, a poll showed The Populus poll more than 8,000 people found.
Meanwhile, Labor leader Jeremy Corbyn has come under pressure for some of his own MPs for saying that "we can not stop" Brexit, just two months after he insisted "Brexit secretary Keir Starmer said a second referendum with the option to remain in the EU should be open. Many Labor MPs say that if Corbyn were to back a second referendum, there would now be a majority in parliament to hold one.
In an interview with The mirror Published on Friday, Corbyn said it was necessary to "recognize the reasons why people vote leave". Luciana Berger, Mike Gapes, Wes Streeting, and Chuka Umunna were among the Labor MPs to criticize the remarks, as a major row brews within the party would have a voted down in parliament. Corbyn reiterated his opposition: "Not really, no," he said. "The referendum took place. The issue now has how to bring people together. "
