in time to see two police motorcycle outriders leading a phalanx of protesters on bikes. There must have been a hundred or so protesters with police pedal-cyclists protecting their flank as they streamed along in the heavy traffic. The whole lot was topped off with a couple of Police rapid-response carriers.
It was a model of police escort efficiency, and the protesters were laughing and chatting with the escort officers as they cycled along. Altogether a very English way of doing things, and there wasn't a trace of any animosity from the car drivers who had to move aside.
