Police officers at the centre of the so-called 'plebgate' scandal have been recalled to face MPs over allegations they misled parliament.
The Chief Constable of West Mercia Police has offered an "unreserved apology" to ex-Chief Whip Andrew Mitchell over the 'Plebgate' meeting.
West Mercia Police chief constable has overturned a ruling that three officers who met Andrew Mitchell had no case to answer for misconduct.
The Independent Police Complaints Commission has said there were "procedural irregularities" in how a final report on police conversations with former chief whip Andrew Mitchell was drawn up.
In the final version of the report, no case to answer for misconduct was made out against any of the three officers under investigation.
But IPCC deputy chairperson Deborah Glass said Chief Inspector Jerry Reakes-Williams, who led the report, mistakenly believed it should reflect the view of the "appropriate authorities" - the senior officers in each of the forces involved.
"It is clear from CI Reakes-Williams's evidence to the Home Affairs Select Committee that this conclusion did not reflect his opinion."
"The 'appropriate authorities' are the final decision-making bodies, and they are entitled to reach a different decision to the conclusions of the investigator. However, this is an entirely separate process. The procedure described above has conflated the two."
Ms Glass said that while she considered the investigation incomplete she does not have the power to re-start it, and so the IPCC will launch its own inquiry to avoid damaging public confidence.
Officers accused of misleading an influential committee of MPs over a meeting with former chief whip Andrew Mitchell will be brought back to apologise.
Police Federation representatives Detective Sergeant Stuart Hinton and Sergeant Chris Jones have been called to appear before the Home Affairs Select Committee for a second time on Tuesday.
The officers are accused of giving "misleading" answers when they gave evidence on October 23. The committee wants the pair "to apologise for misleading it".
Police officers accused of giving misleading accounts of a meeting with former chief whip Andrew Mitchell are facing a new watchdog investigation.
The Independent Police Complaints Commission says it will hold its own investigation into their behaviour after finding "procedural irregularities" in the way the inquiry was dealt with.
Following an alleged confrontation in Downing Street, Mitchell spoke to Police Federation representatives Inspector Ken MacKaill, Detective Sergeant Stuart Hinton and Sergeant Chris Jones in a bid to clear the air.
The officers were all told they would face no action for misconduct over press statements they made following the meeting last year.
Andrew Mitchell deserves an apology from the police officers accused of giving a misleading account of a discussion with the former Chief Whip, the head of the Association of Chief Police Officers said.
Sir Hugh Orde told the BBC's Andrew Marr Show:
– Sir Hugh Orde
I watched every moment of the select committee and it was not a good day for policing.
The stark fact is the other three officers should have apologised in the same manner and style as the chief constables did.
The three police officers accused of giving misleading accounts of a meeting with former chief whip Andrew Mitchell as the "plebgate" scandal erupted should apologise for their actions, the head of the Association of Chief Police Officers (Acpo) has said.

Warwickshire Chief Constable Andy Parker has said he was "embarrassed" that his officers had become involved in a heated anti-cuts campaign in the wake of the Plebgate incident.
"My officers got involved in a political campaign which was ill thought-through and has led to a lot of public confidence issues for us," he said.
"I would certainly like to apologise to Mr Mitchell because this added to the already big impact of the Plebgate campaign and it is embarrassing that my force was involved in the way it was."
The chief constable of West Mercia Police has apologised for the findings of an investigation that initially found three Police Federation officers who met Andrew Mitchell had no case to answer for misconduct.
Chief Constable David Shaw has overturned the earlier finding and written a personal letter of apology to the former Chief Whip.
He has asked for another chief constable to be called in to review the decision not to take action against the three officers.
He told the Home Affairs select committee: "Clearly the buck stops with me and I have to be accountable for a huge range of things that go on.
"It's unedifying and it hurts the force."
Chief Constable David Shaw of West Mercia Police has written to former Chief Whip Andrew Mitchell to offer "a profound unreserved apology" over the 'Plebgate' meeting.
