London - British prosecutors say that a policeman has been charged with misconduct in an incident that has raised questions about the integrity of Britain's largest police force.
Andrew Mitchell, a senior Conservative politician, resigned last year after he was accused of swearing at police and insulting them when they refused to let him cycle through the gate to the prime minister's Downing Street office.
Mitchell is accused of calling them "plebs" - a condescending term for working-class people. He has denied the accusations.
Prosecutors said on Tuesday a police officer, Keith Wallis, is being charged with sending an email to a lawmaker that falsely claimed that he witnessed the incident.
Prosecutors also allege that Wallis arranged for his nephew to support his false account.
