Christmas Eve is the worst possible time for demonstrations but it is different in Russia, where they keep Christmas according to the Julian calendar. So there will be people out again, demonstrating and demanding fair elections (though, really, what they need is regime change).
We, in the West, must try to support them. So, anyone in London on Saturday, who can spare an hour or so, please come to the demonstration outside the Russian Embassy at 12 or soon after. In fact, the demonstration will be in Bayswater Road as the Embassy is in Kensington Palace Gardens, which is private property. Nearest tube stations are Queensway and Notting Hill Gate and there are various buses that go along Bayswater Road.
