The Met have been busted over another undercover cop in the protest movement - this time infiltrating Reclaim the Streets. Officer Jim Boyling took part in an occupation of London Transport offices in August 1996 and, during the subsequent prosecution, didn't reveal his real identity. Which could be, you know, perjury. He also potentially allowed the Met access to how protesters were instructing their legal teams. Which could be, you know, perverting the course of justice. Little things like that.
The new Commissioner, Bernard Hogan-Howe, was about to publish a report into how the Met handles its undercover operatives, which the Guardian understands was going to say something along the lines of "more scrutiny? Pish and widdle. Not necessary" (we paraphrase). Weirdly, that report has now been delayed. If it's discovered that Boyling acted with the agreement of a senior officer, this could be very serious indeed.
