Boris Johnson is clinging onto power this morning after a number of resignations piled more pressure on the Prime Minister to resign.
Northern Ireland Secretary Brandon Lewis quit his Cabinet, telling the Prime Minister the government requires "honesty, integrity and mutual respect" and it is "now past the point of no return".
His departure was soon followed by a string of other ministers as the number of MPs quitting government and party posts since Tuesday evening surpassed 50.
So, who has stepped down from government this morning:
Brandon Lewis
The biggest name to resign so far this morning is Northern Ireland Secretary Brandon Lewis.
He told the PM in a resignation letter that he had "given you, and those around you, the benefit of the doubt".
"I have gone out and defended this Government both publicly and privately," the Northern Ireland Secretary told Boris Johnson in his resignation letter.
"We are, however, now past the point of no return. I cannot sacrifice my personal integrity to defend things as they stand now. It is clear that our Party, parliamentary colleagues, volunteers and the whole country, deserve better."
Helen Whately
Treasury minister Helen Whately has resigned, telling Boris Johnson there "are only so many times you can apologise and move on''.
The MP for Faversham and Mid Kent, said: "With sincere regret I am resigning from HM Government.
"I stood for Parliament because I want to make our country a better place."
"Your vision for our country and your mission to level-up has inspired and galvanised people," she added.
"As Exchequer Secretary I have seen this in practice and been proud to play a part. I have argued that you should continue as Prime Minister many times in recent months, but there are only so many times you can apologise and move on. That point has been reached."
Damian Hinds
Security minister Damian Hinds has resigned, saying: "It shouldn't take the resignation of dozens of colleagues, but for our country, and trust in our democracy, we must have a change of leadership.''
He wrote on Twitter: "It has been a huge privilege and responsibility to serve as security minister. It shouldn't take the resignation of dozens of colleagues, but for our country, and trust in our democracy, we must have a change of leadership."
In his letter of resignation, he wrote: "...more important than any government or leader are the standards we uphold in public life and faith in our democracy and public administration.
"Because of the serious erosion in these, I have come to the conclusion that the right thing for our country and for our party is for you to stand down as party leader and Prime Minister.
"I had hoped you would take this course sooner, of your own volition. But as it has become clear that you still intend to stay, I cannot continue to serve in your administration."
Gareth Davies
Conservative MP Gareth Davies has quit as parliamentary private secretary to the Department of Health and Social Care.
The Grantham and Stamford MP tweeted: "It is with great regret that I have informed the whips office of my resignation as a PPS at the Department of Health and Social Care. It has been a privilege to serve in the role and not a decision I have taken lightly."
George Freeman
Science minister George Freeman has written to Boris Johnson to tell him he no longer has confidence in his leadership.
In a letter, he said: "It is with huge regret that I am writing to let you know that I no longer have confidence in your leadership of our country, Government or party, and am writing formally to Sir Graham Brady to register my support for a change of Conservative Party leadership.
"I do this with a very heavy heart. Our country is facing a series of crises and needs strong leadership, and needs ministers focused on delivering strong and effective government to deliver the priorities for which we won a massive majority only 30 months ago.
"I backed you then and since because of your commitment to make Brexit an inspiring moment of national renewal - of our economy, Parliamentary sovereignty and our place in the world - in the One Nation Conservative tradition on which you stood."
Chris Philp
Technology minister Chris Philp, in his resignation letter to the Prime Minister, told him that the events of the past few weeks meant he could not serve in Government any more.
He told Boris Johnson that it had been a "privilege to serve the people of the United Kingdom".
Referencing the Online Safety Bill, currently moving through parliament, Philp said: "If the Government requires any practical assistance in getting the Bill through Commons Report Stage given the current scarcity of ministers, I would be happy to provide it."
He told the Prime Minister that "integrity, honesty and trust in politics" was important.
"Given events over the past few weeks and months I therefore think that you should resign as Prime Minister and it follows that I cannot serve in your Government any longer."
James Cartlidge
James Cartlidge quit as courts' minister, telling Boris Johnson: "The position is clearly untenable."
