Following these revelations, calls were made for the events to be fully investigated. The Metropolitan Police revealed that the investigation, which had started shortly after the leak of the police log, The operation, "Operation Alice", was led by the head of the Metropolitan Police's
Directorate of Professional Standards, Deputy Assistant Commissioner
Pat Gallan. On 23 December, the
Metropolitan Police Commissioner Bernard Hogan-Howe returned from his holiday to promise "a ruthless search for the truth" of the affair. It was reported on 24 March 2013 that ten police officers and one civilian were suspected of involvement. Seven of those officers and the one civilian fell under Operation Alice, with the investigation into the three Police Federation officers, Ken Mackaill, Chris Jones and Stuart Hinton, being a separate investigation by the
Independent Police Complaints Commission. At the same time, Mitchell started libel proceedings against
The Sun, the paper that broke the story. On 31 March, as a result of the apparent leaking of the report, he lodged a complaint with the IPCC, accusing the police of a continued campaign to destroy his career.
Keith Vaz, chairman of the
Commons Home Affairs committee, said that this illustrated why his committee had always called for the investigation to be run by the IPCC rather than by the police themselves. By April 2013, Operation Alice had cost an estimated £144,000. On 5 September 2014, it was reported that the investigation's conclusion revealed the police had obtained the mobile phone records of the Political Editor of
The Sun without his knowledge, through use of the
Regulation of Investigatory Powers Act 2000, and in breach of the usual safeguards for the protection of journalistic sources. They were thereby able to unmask the identity of the whistle-blower. The whistle-blower alleged that one of the officers said "right, we can stitch him up".
Investigations and arrests In March 2013, three officers from the
Parliamentary and Diplomatic Protection group were arrested: one on suspicion of
misconduct in a public office, one on suspicion of unauthorised disclosure of information to the media and one on suspicion of both offences. Another man, a relative of one of the arrested officers, was arrested on suspicion of "intentionally encouraging or assisting the commission of an indictable offence", relating to misconduct in a public office. In September 2013 it was revealed eight people had been bailed over the issue, including five police officers. The lengthy investigation was criticised by the former
Director of Public Prosecutions,
Ken Macdonald.
Criminal conviction of PC Keith Wallis On 10 January 2014, Police Constable Keith Wallis pleaded guilty at the Central Criminal Court, the
Old Bailey, to a charge of
misconduct in a public office relating to the email he had sent to
John Randall MP. This prompted the Metropolitan Police Commissioner, Sir
Bernard Hogan-Howe, to issue a public apology to
Andrew Mitchell: The evidence against PC Wallis was such that he pleaded guilty. To lie about witnessing something and provide a false account falls way below the standards that I and his colleagues expect of officers. His actions have also negatively impacted upon public trust and confidence in the integrity of police officers. I would also like to apologise to Mr Mitchell that a Met officer clearly lied about seeing him behaving in a certain manner. I will be writing to him offering to meet and apologise in person. I expect my officers to serve the public without fear or favour. Where officers break the law they must expect to be held to account and answer for what they have done. On 6 February 2014, Wallis was sentenced to twelve months imprisonment.
Seven findings of police misconduct Seven police officers were found to have committed misconduct in relation to Plebgate, one criminally, three at the level of
gross misconduct and three more as misconduct but not gross misconduct requiring dismissal from the service. Specifically: • on 26 February 2014 PC Keith Wallis was dismissed for his criminal conduct in this matter and undisclosed business interests; • on 26 February 2014 PC James Glanville was also dismissed for gross misconduct in data handling; • on 30 April 2014 PC Gillian Weatherley was also dismissed for gross misconduct for leaks to the press; • on 21 May 2014 PC Susan Johnson was dismissed for gross misconduct "in relation to honesty and integrity; confidentiality; discreditable conduct and challenging and reporting improper conduct"; • three further officers were found guilty of lower level misconduct.
Federation officers The IPCC investigation of the three Federation officers, Chris Jones, Stuart Hinton and Ken MacKaill, was on hold for much of 2014, pending a judicial review. However, on 3 November 2014, this application was unsuccessful, with the three forces' investigations branded by the administrative court "a car crash" and so legally flawed that they were "invalid and of no effect". Two of these officers were also accused of lying to Parliament in their evidence to the Home Affairs Select Committee in the account they gave of their disciplinary record (stating they had no record when in fact they did), and were recalled by the committee to justify this. They subsequently apologised. ==IPCC conclusions==
