Did I say "buried"?
As far as I saw it then, Farage and Reform (or any other party) have the right to action a private prosecution, especially (as they wrote iin their letter to the Home Secretary) as follows: “We have genuine reason to be concerned that in fact, the CPS is awaiting for the IOPC to find some fault with the police officers, which will then give them a reason not to progress charges against the assailants. This is totally unacceptable.”
