A statement from the Police Federation of England and Wales, which represents tens of thousands of rank-and-file officers, said:
The IPCC had the choice at the outset of this investigation either to conduct an independent, managed or supervised investigation, and it chose to supervise.
Against this factual background, we are therefore shocked that the IPCC Commissioner, Deborah Glass, would then appoint herself judge and jury by releasing her personal view that she disagrees with the findings and asks the public to decide.
It's turning out to be a big week in the life of the story we call "plebgate".
West Mercia Police have confirmed they are reviewing a report on the 'Plebgate' scandal which is alleged to have been fundamentally altered.
Claims have emerged police officers changed the conclusions of a probe into a meeting between Andrew Mitchell and federation members.
