Sue Gray has been looking into boozing in Downing Street - but she used to be the one pulling the pints.
The civil servant has sent her report into Partygate, the scandal which has plagued Prime Minister Boris Johnson and his government since revelations came to light in December 2020, to No 10 today.
Publishing of her findings was delayed due to an investigation by the Met Police in which the PM himself received a fine and No 10 was forced to deny the PM asked Gray to drop publishing the report.
