Several sound systems this time, some were threatened with SOCPA prosecution if they dared to play in the vicinity of Parliament. Cycle police were back after their Christmas/New Year break, about 28 in all - they usually don't turn up at all to the December ride. They barked orders and blocked the ride at some intersections but did a good job of corking and even told off a few drivers. Later they shut down a sound system in Whitehall.
Just before Oxford Circus, a wannabe saboteur threw a glass bottle into the road which shattered into lots of puncturing shards, something to watch out for in future.
