A source close to the privileges committee said Ms Johnson and other attendees could be brought before MPs to explain what happened at the two events.
“What they are deciding is whether the Prime Minister lied to Parliament. To do so they have to go beyond the two elements of what he said,” the source said.
“The Prime Minister says he was given guarantees [that they complied with the rules]. Whose guarantees were these, and what is the truth?
“The committee will want to talk to Sue Gray and maybe Carrie.
“It’s up to them to investigate the alleged part of Abba and the other possible part of the apartment and ask for the papers and witnesses they want.”
The source insisted that the privileges committee had stronger powers than Gray’s investigation to call witnesses and ask for answers. Failure to do so, even by private citizens, could be a disregard for Parliament.
Potential “bombs”
The source described the latest allegations as possible “bombs” and added: “This destroys the quality of Met and Sue Gray’s police investigations. It destroys the suggestion that they cooperated all the time and destroys the argument that the Prime Minister did not lie. “
Labor last night called on the Privilege Committee to investigate the involvement of the Prime Minister and his wife in the meeting on his flat on his birthday.
In a letter to Cabinet Secretary Simon Case, Angela Rayner, Vice President of Labor, urged him to make the messages public and pass them on to the committee because of the “very genuine public interest in getting to the truth.”
Ms. Rayner wrote: “Given the public interest at stake, I request that you make public your correspondence related to this event and your whereabouts on Friday, June 19, 2020 and that you post the relevant messages you have received. , as well as handing them over to the Privilege Committee for consideration as part of their investigation “.
Downing Street has previously admitted that two events to commemorate Mr. Johnson’s birthday took place on June 19: one in the afternoon for which he and his wife received a fixed penalty notice and another with their siblings legally outdoors in your garden. Number 10 had dismissed in January the existence of a third fact as “totally false.”
Dispute version of events
The Downing Street aide alleges that he notified the texts at Gray’s consultation in January. The complainant said they did not want to forward the messages, but said they were willing to come to the cabinet office and show them in person to officials. The office questions this version of events and insists that this offer was not made.
A source said: “Any relevant information delivered to the Cabinet Office has been explored and put into practice. This is how we got to the point where we published the findings last week.
“The individual did not offer to take the messages to the cabinet office, so there was no possibility that the investigation team would read them.”
They added: “The individual refused to provide these messages to the investigation team even though he was asked to provide this relevant information. They indicated that they would provide it to the Met police.”
By the time the assistant made a second offer to show the texts earlier this month, Sue Gray’s research was over. The suggestion that the investigation had not investigated crucial evidence was strongly debated.
