Sue Gray report: South Yorkshire mayor brands Prime Minister Boris Johnson 'unfit for the office he holds'

The senior civil servant investigated 16 gatherings, 12 of which are subject to a Met Police investigation.

The report found that ‘some of the behaviours surrounding these gatherings is difficult to justify’, and found ‘failures of leadership and judgement’ in No 10.

It also condemned the ‘excessive consumption of alcohol’, stating it is ‘not appropriate in a professional workplace at any time’.

PM Boris Johnson said he would not provide a ‘running commentary’ when asked if he was present at a party on November 13.

Dan Jarvis, Mayor of South Yorkshire and Barnsley Central MP said the report is a ‘damning indictment’ of the PM, and it revealed a ‘failure of leadership and judgement’.

“Sue Gray’s report reveals a failure of leadership and judgment at the highest level of government. It is a damming indictment of the Prime Minister,” said Mr Jarvis.

“Twelve parties are now being investigated by the Met, including one held in Johnson’s own flat. He has continually proven himself to be fundamentally unfit for the office he holds.”
