Boris Johnson is set to resign as Prime Minister, it was reported this morning (Thursday, July 7), after he haemorrhaged support among his ministers and MPs.

A No 10 source said Mr Johnson spoke to Sir Graham Brady, chairman of the Conservative 1922 Committee, to inform him of his decision.

He will remain as Prime Minister until a successor is in place, expected to be by the time of the Conservative Party conference in October.

More than 50 MPs have resigned from government or party roles since Tuesday night, when the mass exodus was triggered by the resignations of Rishi Sunak and Sajid Javid from the Cabinet.

Boris Johnson resigns

The Prime Minister had sought to defy his critics and carry on in office, despite warnings from Cabinet colleagues that this was not sustainable.

But resignations continued and Chancellor Nadhim Zahawi – who was only appointed to the role on Tuesday – went public with his call for the Prime Minister to quit.

What has the reaction been to Boris Johnson resigning?

Labour leader Sir Keir Starmer was one of many politicians to give their thoughts on Mr Johnson's decision, saying that he had been "unfit for office" and called for a "fresh start" for Britain.

Meanwhile MEP Guy Verhofstadt was also damning in his words, writing on Twitter: "Boris Johnson's reign ends in disgrace, just like his friend Donald Trump. The end of an era of transatlantic populism? Let's hope so. EU - UK relations suffered hugely with Johnson's choice of Brexit. Things can only get better!"

First Minister of Scotland Nicola Sturgeon also commented, saying: "There will be a widespread sense of relief that the chaos of the last few days (indeed months) will come to an end, though notion of Boris Johnson staying on as PM until autumn seems far from ideal, and surely not sustainable?"

Former leader of the Green Party Caroline Lucas also shared conerns of Mr Johnson not leaving immediately.

She wrote: "Boris Johnson is being forced to resign for being unfit for office as a reckless, untrustworthy, lying, law-breaking rogue Prime Minister with no regard for rule of law or our democratic systems. He must not be allowed to stay on for 3 months after resigning and must go now."

Gary Lineker joked about the situation, posting: "He’s going. Give it to Big Sam for the rest of the season."

Shebab Khan, the political reporter for ITV tweeted: "Last two Prime Ministers (Theresa May and David Cameron) both essentially lost their job because of Boris Johnson. I imagine they’re both quite enjoying watching the current PM also lose his job because of Boris Johnson."

Martin Lewis, the MoneySavingExpert founder provided a different tack in his reponse, calling on the Government to move on quickly to help people with the cost-of-living crisis.

He posted: "I would politely urge the Conservative party to a v quick succession process. We need a working administration at speed.

"This Winter will be catastrophic, pushing millions into poverty with typical energy bills rising to £3,000/yr. We need leaders in office taking action asap."
