SNP Westminster leader Ian Blackford was thrown out of the Commons chamber for accusing Boris Johnson of "lying".
In a heated statement after the Prime Minister said he is "sorry", Mr Blackford told the Commons: "This Prime Minister has lied and misled the House”.
Visibly emotional, Lindsay Hoyle the Commons speaker asked the SNP Westminster leader to withdraw the accusation.
As Mr Hoyle appeared to plead with Mr Blackford to take back his comment, Mr Blackford replied: “That the Prime Minister may have inadvertently misled the House.”
Sir Lindsay countered: “To help me help the House, you’ve withdrawn your earlier comment and replaced it with inadvertently?”
Mr Blackford refused a number of times.
As the Speaker prepared to formally boot Mr Blackford out, the SNP Westminster leader left himself.
As he left the Commons chamber, Mr Blackford said: "It's not my fault if the Prime Minister can't be trusted."
During his speech Mr Blackford had told MPs: "So here we have it. The long-awaited Sue Gray report, what a farce. It was carefully engineered to be a fact-finding exercise, with no conclusions. Now we find it’s a fact-finding exercise with no facts.
“So let’s talk facts. The Prime Minister has told the House that all guidance was completely followed, there was no party, Covid rules were followed and that ‘I believed it was a work event’.
“Nobody, nobody believed it then. And nobody, nobody believes you now, Prime Minister. That is the crux – no ifs, no buts – he has wilfully misled Parliament.”
Before Mr Blackford took to his feet, Mr Johnson told the Commons he was “sorry for the things we simply didn’t get right and also sorry for the way that this matter has been handled”.
Mr Starmer responded and said: "Many have been overcome by rage, by grief, even guilt. Guilt that because they stuck to the law, they did not see their parents one last time."
He even quoted Margaret Thatcher in noting: “The first duty of government is to uphold the law. If it tries to bob and weave and duck around that duty when it is inconvenient, then so will the governed.”
But Mr Johnson hit back and accused the Labour leader of failing to prosecute Jimmy Savile as he hit back at Labour criticism over the Sue Gray report.
The Prime Minister said: “The report does absolutely nothing to substantiate the tissue of nonsense that he has said. Absolute nonsense.
“Instead this leader of the opposition, a former director of public prosecution – who used his time prosecuting journalists and failing to prosecute Jimmy Savile, as far as I can see – he chose to use this moment to continually pre-judge a police inquiry.
