A police officer is due to appear in court today accused of misconduct in public office over the Plebgate affair.
Pc Keith Wallis is facing claims he sent an email to Conservative deputy chief whip John Randall, who was his MP, wrongly claiming that he had seen what happened in Downing Street last year.
A row erupted after then-chief whip Andrew Mitchell became involved in a heated confrontation with an officer after he was refused permission to cycle through the main gate.
Mr Mitchell admitted swearing but denied the officer's claim that he had used the word "pleb".
Pc Wallis, based within the Met's Diplomatic Protection Group, is due to appear at Westminster Magistrates' Court in London.
The Independent Police Complaints Commission (IPCC) announced last month that Wallis and four other colleagues will face gross misconduct proceedings over the row.
