Each day this week Plebgate has made the headlines and the story is now moving rapidly from police conspiracy to police cover up. From Plebgate to Plodgate!
Eight people, including four police officers, have been arrested and bailed over the September 2012 row at the Downing Street security gates. The Crown Prosecution Service is currently considering charges.
On Sunday it emerged a new senior police whistleblower has come forward and he confirms there was a police conspiracy against Mitchell.
On Tuesday, the IPCC questioned the "honesty and integrity" of the officers, and said West Mercia Police had been wrong to conclude they had no case to answer for misconduct.
The Independent Police Complaints Commission yesterday ruled there was evidence those officers set out to deliberately discredit Mr Mitchell and they should face gross misconduct proceedings
Association of Chief Police Officers' chairman Sir Hugh Orde said the incident demonstrated the "critical" need for a fully independent police investigation system.
He said: "What I am clear on is it requires an explanation from the leaders of those three police forces - all of whom have very clearly said they want to come to the home affairs select committee and be held to account in an open and transparent forum by elected MPs, to explain their side of the story."
Home Secretary Theresa May said the IPCC's report "made troubling reading
Home Affairs Select Committee chairman Keith Vaz said David Shaw, chief constable of West Mercia Police, would be summoned before MPs next week to explain why misconduct hearings had not been held.
BBC home affairs editor Mark Easton said the issue of public trust in the police service in England and Wales was central to the row.
What made the matter so troubling, was the suggestion that when entrusted with investigating wrongdoing, police chief constables had not taken appropriate action.
So we now await possibly three Chief Constables 'up before' the Home Affairs select committee to answer charges of why they are so weak and fail to stand up to the Police Federation who are a union out of control.
