Why are MPs resigning and withdrawing support?
Mr Sunak and Mr Javid stepped down within minutes of each other on Tuesday.
It came just hours after Downing Street confirmed Mr Johnson was informed that former deputy chief whip Chris Pincher had been investigated over his conduct when he was a Foreign Office minister - following days of denials from Downing Street that the PM knew.
Now ex-chancellor Mr Sunak said in his resignation letter that "the public rightly expect government to be conducted properly, competently and seriously".
"I believe these standards are worth fighting for and that is why I am resigning," he adds.
He also hinted at splits on economic policy, pointing to the need to "work hard, make sacrifices and take difficult decisions" – a planned joint speech with the prime minister had made it clear "our approaches are fundamentally too different".
Mr Javid said the public had concluded that under Mr Johnson the Tories were not “competent in acting in the national interest” and the prime minister could not offer “humility, grip and new direction”.
Their letters triggered a series of resignations from other ministers on Tuesday evening and more followed on Wednesday morning.
