Plebgate police officers dismissed by Met

In a statement, the Metropolitan Police revealed that Andrew Mitchell attended both misconduct hearings for former Pcs Keith Wallis and James Glanville, as an "interested party".

The Met spokesperson said: "Misconduct hearings are considered a privateprocess. As such, we treat theinformation raised within them as confidential.

"This is set out in the statutory regulations governing police misconduct proceedings. However, given the public interest in this investigation the MPS, will publicise the outcomes of the hearings."

Andrew Mitchell, then chief whip, was involved in a heated confrontation with another police officer, Toby Rowland, after he was refused permission to cycle through the main gate of Downing Street on September 19, 2012.

Mr Mitchell, who was accused of calling the officer a ''pleb'', was forced to resign his post following a month of intense media interest in the story.

The Metropolitan Police has also announced that a second officer has been dismissed following their involvement in the 'plebgate' scandal.

James Glanville, who was a serving PC in the Diplomatic Protection Group, was arrested in January last year. He was later told he would face no criminal action but the police watchdog (IPCC) and the force agreed their was a case to answer for gross misconduct.

Granville was not on duty at the time of the 'plebgate' incident, but investigations found that later that evening he passed information about the incident to the Sun newspaper.

He later provided the newspaper a photo of PC Toby Rowland's email that he sent to his supervisors, which he got from another colleague who had been on duty at Downing Street that night. He subsequently lied about his actions in statements given to detectives from the Alice team.
