Lib Dem leader Ed Davey said: “Everyone knows Boris Johnson broke the rules and lied to the country. 

“It’s time Conservative MPs did their patriotic duty, listened to their constituents and stood up for decency by sacking Boris Johnson. 

“He must go before he does our country any more harm.”

His party colleague Layla Moran said: “For bereaved families, frontline workers, and people who gave up so much, this report does not dull their anger. 

“Responsibility for “failure of leadership and judgement” lies with Boris Johnson alone. 

“He knew what took place. 

“He saw events in his own back garden. 

“He should resign.” 

Green Party leader Caroline Lucas, MP for Brighton Pavilion, said: “Utterly damning findings in the Sue Gray Report and this from a report that’s been gutted thanks to an 11th hour intervention by the Met.

“If the PM thinks the ‘partygate’ scandal is now over, he’s wrong. 

“People won’t forget that while they suffered, Number 10 partied and he sometimes joined in.

“‘Behaviour is difficult to justify’, ‘A serious failure to observe the high standards expected’, ‘Failures of leadership and judgment’, ‘Staff felt unable to raise concerns’. 

“What an indictment of Johnson’s leadership. Any self-respecting PM would resign after this.”

Telegraph readers’ response to seismic day in Parliament 

Anthony Smith: “I obeyed the Covid rules. The last view I had of my father was him sitting up in the back of an ambulance waving goodbye to me. 

“It was my last sight of him alive and I am haunted by his final farewell to me. 

“So Boris, do the decent thing and resign there is no excuse for your behaviour and that of your colleagues in No 10. 

“If you needed to be told your behaviour was inappropriate you are unfit to be PM.”

Maggie Lavan: “Now I’ve seen the debate and witnessed the vile demands from third-rate politicians that Boris should go I will definitely renew and strengthen my support for him.”

Peter Jarman: “I don’t doubt that if there was an election tomorrow that the Government would win. The other parties are unelectable. 

“The problem is we have a leader in this country who does not represent the people. He lies, he is immoral and thinks he is above the law.

“There must be someone in Parliament that is better than this.”

Members of the public’s rage over report

A man who was fined almost £2,000 for breaking lockdown rules has called for a refund and an apology after the release of the Sue Gray report.

Bryn Richards, a university student from Norwich, was charged £1,995 for participating in a gathering outdoors of more than two people in November 2020, during the UK’s second national lockdown.

The 38-year-old claimed he was arrested after interacting with participants of a libertarian, anti-lockdown march while out for a walk in the city, adding he was “caught in the crossfire, between the police and the protesters”.

“If any member of the public did what they did, they’d most assuredly have been fined, without any hesitation by the police,” he told PA.

“I had £2,000 seized from me for doing much less than what they did.

“Quite frankly, I want that money back, and I want a formal apology.”
