London's Metropolitan Police force has sacked two officers for their roles in the "Plebgate" scandal which led to the resignation of a government minister.
Police constables Keith Wallis and James Glanville, who were both members of Scotland Yard's elite diplomatic protection squad, were sacked for "gross misconduct".
Wallis is already serving a 12-month jail sentence after he falsely claimed to have witnessed a row between then-government chief whip Andrew Mitchell and an officer at the gates of Prime Minister David Cameron's Downing Street residence in September 2012.
Wallis admitted in court that he had lied in an email to his local MP that he was present during the row, and admitted arranging for his nephew to support the claim.
Glanville leaked information about the row to Rupert Murdoch's tabloid newspaper The Sun, although he was not on duty at Downing Street at the time, Scotland Yard said in a statement.
The force said he had breached professional standards of confidentiality and other matters.
Glanville was arrested in January 2013 but told in November that he would not face charges.
The pair were sacked after disciplinary hearings that were held in private under police rules.
Mitchell was forced to resign over claims in The Sun that he called officers guarding Downing Street "f***ing plebs" because they refused to let him go through the main gate with his bicycle, adding that they should "know your f***ing place".
Mitchell admitted he swore but denied using the word "pleb", a derogatory term for the lower social classes.
He resigned over the so-called "Plebgate" row a few weeks later but questions about the honesty of Britain's police have rippled out from the scandal ever since.
