Plebgate officers to give evidence to MPs Three police officers caught up in the so-called Plebgate row are to be grilled by MPs today as part of a bumper evidence session on the ongoing affair. Police Federation representatives Inspector Ken MacKaill, Detective Sergeant Stuart Hinton and Sergeant Chris Jones were accused of trying to discredit former Tory chief whip Andrew Mitchell after meeting him in October last year. The officers, who were representing the forces of West Mercia, Warwickshire and West Midlands, were spared misconduct proceedings by an internal investigation. But the Independent Police Complaints Commission (IPCC) later disputed the findings and said there were issues of "honesty and integrity" among the three men. The federation representatives will give evidence to the Home Affairs Select Committee before the chief constables from all three forces - Andy Parker of Warwickshire Police, David Shaw of West Mercia Police and Chris Sims of West Midlands Police - also appear. Earlier in the day, Chief Inspector Jerry Reakes-Williams, who led the internal inquiry into the allegations, will give evidence, as will Dame Anne Owers and Deborah Glass, the chairwoman and deputy chairwoman of the IPCC. Mr Mitchell met the three officers after he was accused of calling officers guarding Downing Street "plebs" in a foul-mouthed rant as he was asked to cycle through a side gate on September 19 last year. The Tory MP said he wanted to sit with Mr MacKaill, Det Sgt Hinton and Sgt Jones to "clear the air." A transcript shows Mr Mitchell apologised for swearing at the police officers but denied using the word ""plebs"," while in comments made after the meeting Mr MacKaill claimed the former Tory chief whip refused to provide an account of the incident. West Mercia Police conducted an internal investigation into claims the three officers were trying to discredit Mr Mitchell but concluded there was no case to answer for misconduct or gross misconduct. However, the IPCC concluded they should have faced a misconduct panel. Prime Minister David Cameron insisted Mr Mitchell was owed an apology by police and said the conduct of the officers was ""not acceptable"." The three officers earlier this week apologised for making a public statement after the meeting at Mr Mitchell's Sutton Coldfield constituency office but did not retract the comments made. The Crown Prosecution Service is considering whether to bring criminal charges following Scotland Yard's £230,000-plus investigation, known as Operation Alice. Eight people including five police officers arrested under the investigation were re-bailed. Plebgate: Police owe Mitchell an apology - Cameron
