The whole plan is now clear.

Deny anything happened, but it complied with the rules anyway.
PM/Met Commissioner consult.
Met place hands over eyes and ears and say they've seen/heard no evidence.
When it gets too compelling, PM commissions an enquiry by a civil servant to report directly to the PM, the PM thus retains ultimate control of the proceedings and reporting
Met Comm says they will only carry out an investigation if the potential perpetrators knew or should have known it was against the law (when did that apply to the rest of us?)
When it becomes clear that evidence will be "embarrasing", pass snippets to Met and they say they will now start an investigation.
This means that either they take control of proceedings, the Gray report is seriously diluted and restricted and it takes, what, a couple of years, maybe five, for the Met to come to any conclusion (plus the DPP have to get off their backsides) or if the Gray report is published and includes proper incriminating evidence then the Met claim that a fair trial would be impossible and the investigation is halted, PM claims he is exonerated.
PM keeps full control, kicks the can far far down the road with the intention of delaying anything useful coming out before the next general election.
Job done ........ for now.

Putin would be proud of it.
