What do we know about the Sue Gray report?

It's finally happening! This is the week the infamous Sue Gray report into partygate will be released. Details are few and far between, although we do know that the Prime Minister will be mentioned by name in the document. Mutterings from Tory HQ are that this is not going to be a good week for the government but not the end of Boris Johnson. Only time will tell.
