Boris Johnson must "urgently explain" why he had a "secret" meeting with Sue Gray over her Partygate report, Labour have said.
It follows reports the top civil servant met with the Prime Minister a month ago, to discuss the publication of her long-awaited probe into lockdown-busting Downing Street parties.
Mr Johnson is said to have spoken to Ms Gray about where she thought Scotland Yard were with their own investigation and interviews with civil servants, according to Sky News.
