Sunday’s Observer quotes Lib Dem MP Tom Brake as pointing a finger at two plain clothes policemen he believes were acting as agents provacateurs at the G20 protests last month.  Tom Brake was, as readers will recall, acting as an observer during the protests, and is set to give evidence at a committee on human rights today.

“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.”
