You’ll remember how, at the G20 demonstrations, a passing newspaper vendor died about being struck by a policeman. Now a British MP says he saw an undercover cop acting as a provocateur at the demonstration:

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.
