Very Important Pedestrians: Oxford Street and Regent Street have been closed to traffic today in attempt to attract crowds of shoppers to the capital's two main shopping streets. It's not like the pavements are usually quiet, you understand, but today it's possible to step off into the road without being mown down by a passing double decker. Crowds of shoppers have duly turned up, and are swarming around the big (and little) stores snapping up Christmas goodies like there's no tomorrow. The roads aren't completely clear, though. At the intersection of the two streets a group of mysterious white inflatable globes is causing almost as much congestion as the usual traffic lights. Mobile musical entertainment is being provided by bagpipers and a couple of Sally Army brass bands, as well as the odd steel band and ethnic drumming ensemble. Elsewhere there's free mulled wine (if you know where to look), plus the usual balloon-sculpting elves and stilt-walking angels who gravitate towards events such as this. Beside Tottenham Court Road station people are queueing to enter Banksy's annual "Santa's Ghetto" exhibition (photos here). And outside John Lewis I stumbled upon a photocall by Ken Livingstone flanked by a row of grinning Santas (alas, they all buggered off into the nearest department store before I could grab a photo myself). Today's event seems to have been a great success (so long as you weren't trying to ride a bus anywhere nearby), and can only hasten the day when Oxford Street is pedestrianised for good. As for the Christmas shopping, though, it struck me that more pedestrians just means busier shops and longer queues, so I resisted. Maybe I'll return when the cars do - it should be quieter then.
