Boris Johnson fights to save his premiership amid a mass walkout of ministers, and growing Tory rebellion.
Prime Minister's Questions: He said that he had a "colossal mandate", and would "keep on going".
However, a number of Tories are still leaving government and party positions. Backbenchers have also withdrawn their support.
As questions continue to swirl about the future of the PM, Tory party bosses will meet at 16.00 BST.
Conservative rebels want to change party rules in order to allow Johnson to face a threat.
He was able to survive the vote and would not be subject to another challenge for one year under current rules.
He will then face additional leadership questions when he appears before the Liaison Committee, which is made up of senior MPs.
After the resignations of Health Secretary Sajid Javid and Chancellor Rishi Unak, Mr Johnson's premiership is in crisis.
After a dispute over the appointment of Chris Pincher deputy chief whip by Mr Johnson earlier this year, they quit within minutes of one another on Tuesday.
There has been a wave of resignations following their departures. Several ministers are now leaving. Among the most recent departures are Kemi Badenoch and Alex Burghart.
According to a senior ally of Prime Minister, it is now up to him to decide how he leaves. He also stated that the situation was not sustainable.
PMQs: Labour leader Sir Keir Sternmer stated that the Conservatives were now a corrupt party, defending the indefensible.
He made a slam of ministers who resigned in the last days, claiming that their decision to not quit now was an indication they were lacking any "shreds of integrity".
He mocked those who had remained in their posts, calling them "Z list casts of nodding dogs", and keeping the PM in office.
He said they were only in office "because no-one else wants to debase themselves any more", and called them the "charge for the lightweight brigade".
Gary Sambrook, Tory backbencher and Tory MP, accused the PM of blaming others for his mistakes. He was applauded when he called on him to resign.
David Davis, a fellow backbencher, urged Johnson to resign in January. He repeated his appeal for Johnson to resign before it "becomes impossible for government to do their job".
Johnson refused to leave, saying he would "continue to fulfill the mandate I was given".
"When a prime minister is in difficult circumstances, he must continue to work - that's what I'm going do."
Sometimes politics can be subtle. There are days like today.
As you sat in the Press Gallery watching Prime Minister's Questions at lunchtime, Boris Johnson's authority was dripping away.
It was evident in the faces of Conservative MPs as their backbenchers sat silently, despite all the noise from the opposition benches.
This was Johnson's most difficult PMQs since the general election.
It's only lunchtime.
After PMQs, Mr Javid stated that "treading the tightrope of loyalty and integrity" was becoming "impossible" in a resignation statement.
He said, "At some point, we must conclude that enough is sufficient." That point, I believe, is now.
M. Johnson admitted that it was a "bad error" to appoint Mr Pincher despite knowing about misconduct allegations against him.
After the Partygate scandal, which caused discord between the PM and his backbenchers, as well as unhappiness about tax increases, the row over his appointment is a matter of contention.
Many key cabinet ministers, including Liz Truss (foreign secretary) and potential challenger to the prime minister, have rallied around him.
The rebel Tories, however, want to use a upcoming vote to backbench 1922 to end the year-long gap in contests. This would make it possible for him to face another challenge later in the summer.
Rebel Tory MPs could attempt to overthrow him later in the summer or in the fall if party bosses alter the one-year rule regarding leadership challenges.
Johnson would be required to resign if he loses a vote in no confidence in Parliament.
He would need to resign if he didn't, possibly because of cabinet pressures like Margaret Thatcher, or after a new wave of ministerial resignations.
