Thanks for the new thread, Rhino.
One thing puzzled me about the part of the SG report released today. It says, in the appendix, that one of her appointed tasks was to report on attendance at the various events, but she has not done so - even in the case of the four events that the Met are not investigating. Perhaps the police insisted that no names were mentioned, whatever the event.
Incidentally, anyone wanting to see what SG finally submitted can find the document at www.gov.uk - enter "Sue Gray" in the search box, and it is the first thing to come up (a rather slim PDF of 6 pages, excluding the introductory material and annexes).
