A spokesman for the prime minister has repeatedly refused to disclose whether Mr Johnson’s actions at the Wednesday meeting were legal under the coronavirus law.
The Prime Minister convened a meeting of the backbench committee of members of Parliament in 1922 on the same day written by Downing Street on Twitter: “The gathering of more than 30 people is illegal. Breaking the rules could cost thousands.”
The Bloomberg news agency said several sources in the room admitted that 50 people were present, although they were marked by about 29 people to prevent the spread of coronavirus.
Mr Johnson noted that his colleagues were full of “cheekbones” when he delivered his speech to the 1922 committee, Bloomberg said.
He was challenged to deny the report, a spokesman for Mr Johnson said: “Because this was a political event, I don’t know any more details. I will have to pass it on to my political colleagues.”
Asked why the prime minister did not leave, the spokesman also said: “I do not know the details, it was a political event. I would refer you to our political colleagues.”
Asked if National Assembly Speaker Sir Lindsay Hoyle, who was furious with MPs following the public outcry in parliament, expressed concern, the speaker said: “As a public servant, I do not know about political events.”
When pointed to a security question, he added: “A question about something I don’t know the details of.”
Finally he was asked to clarify whether Mr. Johnson complied with his appeals rules, the spokesman clarified: “Yes.”
The exchange took place at a daily hospitality conference for political journalists, where a spokesman for the prime minister answered questions on a variety of topics.
The invitation sent to all members of the Tory Parliament before the 1922 committee meeting promised that “we would respect the social distance as far as possible”.
Sir Graham Brady, chairman of the powerful commuter committee of old riders, stressed that “one distance is kept in the community once and for all”.
But former Liberal Democrat activist Wera Hobhouse called for a “full investigation” and said the reports “undermined faith in the government and ultimately contributed to the implementation of the government’s public health messages”.
A spokesman for the House of Commons said: “The UK Parliament is a safe working environment for COVID-19, which meets all government guidelines.”
It comes days after Secretary of Defense Ben Wallace apologized for shaking hands with his colleagues before he entered what was being charged as the first cabinet meeting that had people unrelated to the new Parliamentary term.
