“The Prime Minister meets his civil servants all the time.”

“Sue Gray is skilled, and has the best stage of integrity,” he added. “She is independent, the Prime Minister will never intervene, interfere, in the investigation.”
The BBC initially reported that the discussions touched on whether or not photographs could be revealed to the general public, and that Ms Gray initiated the assembly “to clarify her intentions” for what would occur as soon as the police investigation concluded.
However, a spokesman for the inquiry disputed this account of occasions, whereas a No 10 supply insisted the request for the assembly didn’t come from Mr Johnson.
It has additionally been reported that the assembly was instructed by a No 10 official, whereas the calendar invitation was despatched by Ms Gray.
