An MP who was involved in last month's G20 protests in London is to call for an investigation into whether the police used agents provocateurs to incite the crowds.
Liberal Democrat Tom Brake says he saw what he believed to be two plain-clothes police officers go through a police cordon after presenting their ID cards.
Brake, who along with hundreds of others was corralled behind police lines near Bank tube station in the City of London on the day of the protests, says he was informed by people in the crowd that the men had been seen to throw bottles at the police and had encouraged others to do the same shortly before they passed through the cordon.
Brake, a member of the influential home affairs select committee, will raise the allegations when he gives evidence before parliament's joint committee on human rights on Tuesday.
"When I was in the middle of the crowd, two people came over to me and said, 'There are people over there who we believe are policemen and who have been encouraging the crowd to throw things at the police,'" Brake said. But when the crowd became suspicious of the men and accused them of being police officers, the pair approached the police line and passed through after showing some form of identification.
Brake has produced a draft report of his experiences for the human rights committee, having received written statements from people in the crowd. These include Tony Amos, a photographer who was standing with protesters in the Royal Exchange between 5pm and 6pm. "He [one of the alleged officers] was egging protesters on. It was very noticeable," Amos said. "Then suddenly a protester seemed to identify him as a policeman and turned on him. He legged it towards the police line, flashed some ID and they just let him through, no questions asked."
Amos added: "He was pretty much inciting the crowd. He could not be called an observer. I don't believe in conspiracy theories but this really struck me. Hopefully, a review of video evidence will clear this up."
Were the police stirring up trouble just so that they could beat the crap out of people, or was there something even more sinister behind this?
I can't help but feel that the police in this country are getting way out of line. This kind of behaviour is going to be to the police what expenses were to politicians. Mind you would shutting down the ACPO and sacking all the senior porkers be such a bad thing?
