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.
In questioning the 'integrity' of plebgate officers the IPCC has dramatically raised the stakes in standoff between politicians and police.
– Police Federation statement
We welcome the decision by the CPS that there was insufficient evidence to show that the officer at the gate lied in his account and that there was insufficient evidence to show that Mr Mitchell was the victim of a conspiracy of misinformation.
We have always been concerned by the selected information that has been put into the public domain and it is noteworthy that the CPS came to its conclusions after reviewing all the evidence, including unedited CCTV footage from Downing Street.
The police officer charged over the 'Plebgate' affair allegedly sent an email to his MP over the incident but it is claimed he did not witness the exchange between Andrew Mitchell and Downing Street officers, the Crown Prosecution Service said.
A CPS statement said: "We have also received evidence in relation to PC Keith Wallis who sent an email to the deputy chief whip, John Randall who was his MP, saying that he had witnessed the incident.
"We have decided, having carefully considered the evidence in accordance with the Code for Crown Prosecutors, that there is sufficient evidence to charge PC Wallis with misconduct in a public office and that it is in the public interest to do so.
"I should make it clear the misconduct allegation relates to evidence that PC Wallis falsely claimed to have witnessed the incident, not to how the incident was described in his account.
"PC Keith Wallis has been charged and is required to attend Westminster Magistrates’ Court on 16 December 2013."
We have considered all of the evidence in this case, including previously unseen, unedited CCTV footage from Downing Street, not referred to by the media.
Taking it all into account, including the accounts of the officer at the gate of Downing Street and that of Andrew Mitchell MP before, during and after the incident, we have found that there is insufficient evidence to show that the officer at the gate lied in his account.
– Alison Saunders, Director of Public Prosecutions
The CPS has also found that there is insufficient evidence to show that Mr Mitchell was the victim of a conspiracy of misinformation.
With insufficient evidence to show that the officer at the gate lied in his account, we must consider other matters, as set out below, on that basis.
I have, however, authorised one officer to be charged with one count of misconduct in public office.
PC Keith Wallis has been charged with misconduct in public office over the Andrew Mitchell "plebgate" affair, the Crown Prosecution Service said.

Detective Sergeant Stuart Hinton from Warwickshire has told MPs he was sorry for any distress caused to MP Andrew Mitchell and his family over Plebgate. A second officer Sergeant Chris Jones from the West Midlands force said he was unable to apologise for something he had not done.
Sgt Chris Jones was forced to reveal that 13 complaints had been made against him during his 28-year service, with none resulting in any misconduct proceedings.
The issue arose as the committee was questioning Sgt Jones for the second time after he failed to mention any disciplinary proceedings during his first appearance.
Sgt Jones also told the Home Affairs Select Committee that he did not feel responsible for any distress Andrew Mitchell or his family had been subjected to in the wake of the 'plebgate' scandal.
The second police officer to speak to the Home Affairs Select Committee has said he will not apologise.
Sgt Chris Jones said he "can't apologise for something I haven't done."
Sgt Jones was asked if he wished to apologise to Andrew Mitchell and his family for the distress they have suffered.
A Police officer involved in the so-called plebgate row has apologised to MPs for "inadvertent inaccuracies" in his last appearance at home select committee.
He said there was no intention to mislead the committee.
Detective Sergeant Stuart Hinton also apologised to the Home Secretary Theresa May for referring to her as "this woman" during the previous hearing.
The Labour shadow home secretary Yvette Cooper says the Commons home affairs select committee's "serious and troubling" report warrants an overhaul of police accountability standards following the plebgate affair.

Andrew Mitchell [Sutton Coldfield MP] has already waited too long for the result of these investigations and these events are casting a long shadow over the vital and much valued work police officers do across the country.
Two of the three Police Federation representatives caught up in the plebgate affair are expected to appear in front of MPs today to face allegations they misled parliament over the plebgate scandal.
The officers are expected to respond to claims at a meeting of the House of Commons Home Affairs Select Committee that they gave misleading answers at a hearing last month.
HASC chairman Keith Vaz made clear he expected Detective Sergeant Stuart Hinton, from Warwickshire Police Federation, and Sergeant Chris Jones, of West Mercia Police Federation, to attend tomorrow's meeting.
Following an internal inquiry, the officers and Inspector Ken MacKail were told they would face no action for misconduct over statements made following a meeting last year with Sutton Coldfield MP Andrew Mitchell who, it was alleged, called police officers guarding the Downing Street gates "plebs."
After taking evidence from the three officers on October 23, the committee published a report yesterday which found their evidence was "possibly deliberately" misleading, lacked credibility and was contradictory.
