Top civil servant Sue Gray has sent her long-awaited report into the Downing Street Partygate saga to No10.
Hard copies arrived in the building this morning and it is expected to be published later today - followed by statements to Parliament and the nation by Boris Johnson.
It's thought the report was only available in one room. It comes after Boris Johnson was accused of lying to Parliament after bombshell pictures emerged of him raising a glass of fizz at an event he denied took place.
