Dissatisfaction over Ms. May's leadership took considerably after having submitted plans for the law on the readmission agreement – the legislation tion of the agreement between Great Britain and EU on the conditions of Brexit.
It contained a number of concessions designed to provide bipartisan support, including new guarantees for workers' rights, environmental protection and the Northern Ireland border, as well as a "customs compromise".  At the latest: Reaction to the Brexit compromise offer of the Prime Minister
But the Brexitians in their own party reacted angrily, especially with a promise to give it. Members vote on another referendum if they support the bill.
Ms. May insists that this is Parliament's "last chance" to complete Brexit, Interior Minister Sajid Javid.
Foreign Minister Jeremy Hunt also called for a private meeting with the Prime Minister.
Laura Kuenssberg, however, said the prime minister had refused to meet the ministers – both were considered as possible candidates for the next conservative leader – and instead seemed determined to "tame" it.

- Prime Minister under fire for new Brexit plan
- Is the & # 39; new & # 39; Brexit deal from May actually new?
Tom Tugendhat wrote in the Financial Times: "Leadership matters, it has been too long," he said. "That can only change with a new Prime Minister."
Former Minister Tim Loughton said it was "very sad" but it was time for her to leave. Another, Stephen Crabb, said there must be a new prime minister. "within a few weeks".
Familiar critics also amplified the shouting after her resignation.
Leading Brexitian Steve Baker said it was "not personal" but "about the future of the country", and his party had to "re-assemble a governing coalition ready to take us out of the EU" under one new leader.
For many months, there have been doubts about the leadership of Theresa May.
She herself has more or less said that she will resign next month.
But today something else happened, the mood has really changed.
More and more conservatives are publicly saying they have to quit as soon as possible.
Ministers told me privately that she has now reached the end of her line. However, number ten is relentless that nothing has really changed, she'll go ahead and still try to get her Brexit deal.
But it seems the government has almost collapsed.
And it is just not clear at this moment if they will really be able to persevere.  The UK was due to leave the EU on 29 March, but postponed to 31 October after the Commons rejected Ms. May's withdrawal agreement with Brussels three times.
Attempts to find a bipartisan compromise over formal talks failed last week, and Labor leader Jeremy Corbyn has rejected Ms. May's attempts to win over his MEPs for their Brexit withdrawal plan.
Mr. Corbyn said her "brave new deal" was really a "repackaged version" of her failed withdrawal agreement. Added, "No Labor MP can vote for an agreement with the promise of a prime minister with only days to spare in her job."
He said Brexit had "split our society and poisoned our democracy", but claimed that Mrs. May's deal was "not a real compromise".
Among her critics in the House of Commons, Ms. May said earlier, "Over time, another Prime Minister will stand by this shipping box, but while I'm here, I have a duty to be clear about the facts with the House.
"If we want to do Brexit in this Parliament, we have to pass a bill on a revocation agreement and we will not do that without voting on the issues that split us the most," she said.
Ultimately, it is our job in the House of Representatives to make decisions and not disappoint. "
" Must Stop "
Westminster SNP leader Ian Blackford – who supports another referendum to stay in the EU – said It was time for the Prime Minister to go after he "lost the trust of the public."
"This deal is dead," he added.
The DUP, representing the government of Mrs. May s also rejected the vote for the bill.
Liz Kendall of Labor supported the call for public voting and informed Ms. May that she would not receive enough support for her bill from the opposition without including a confirmatory ballot as part of the agreement – rather than just voting on whether they should have one.
But Conservative MP Vicky Ford said: "We can not leave our country in this uncertainty, it has to stop, the whole house has to stop saying no to everything on the table just because it's not our favorite dish. " 19659003] "If we vote for this bill, we can go ahead and start discussing the next stage."
What is in the withdrawal agreement?
Ms. May brings the draft right of withdrawal, which is required to implement her consent into British law, to Parliament in early June.
In an attempt to win over MPs throughout the House, she announced the following concessions:
- A Commons vote guarantee of holding another referendum on the government's Brexit deal
- A vote on various customs options, including a government proposal for a temporary customs union for goods – which Mrs May called a "customs compromise"
- A legal obligation for the UK to "look for alternatives" to replace the Northern Ireland backstop by the end of 2020
- . When the backstop comes into force The bill would guarantee that Northern Ireland remains in line with the rest of the UK and is in the same customs territory Standards
- A legal obligation to seek changes to the political statement on future relations with the EU  What are the Tory Leadership Rules?
