Police officers protest outside Andrew Mitchell's constituency office A police officer hands out leaflets outside Andrew Mitchell's office in Sutton Coldfield. Police officers wearing T-shirts emblazoned with the slogan "PC Pleb and Proud" have gathered outside Andrew Mitchell's constituency office, accusing the prime minister of failing to "get to the bottom" of the chief whip's angry outburst. Officers from three branches of the Police Federation - West Midlands, West Mercia and Warwickshire - congregated at the office in Sutton Coldfield, Birmingham. The federations brought forward the launch of their poster campaign against police funding cuts after Mitchell was accused of calling Downing Street police officers "plebs" in a foul-mouthed rant last week. The launch had been scheduled to take place on Friday in central Birmingham, the city that will host the Conservative party conference from 7 October. Ian Edwards, chairman of West Midlands Police Federation, said: "We feel the prime minister has failed to get to the bottom of this matter. It cannot be right that Mr Mitchell can deny making the comments attributed to him, contrary to the police officer's notes, and yet not come out and say what he did say. If he did call police officers plebs, and we have no reason to doubt the integrity of the officers involved, it's just another sign of the disrespect the Conservatives, the once heralded as the party of law and order, show to the police service.
