My usual ride home from work takes me along the Albert Embankment as far as the London Eye. East of Westminster Bridge, it's London's equivalent of a seafront. The old County Hall has been turned into a theme park, and there are ice creams, doughnuts, swathes of silver-painted street performers pretending to be statues, Michael Jackson look-alikes, Charlie Chaplin impersonators, assorted buskers and meandering international tourists on the walkway towards the Royal Festival Hall.
Except last week it was all happening on the north side of the river. The bagpiper on Westminster Bridge had the place to himself while everyone headed off, like me, to see Gordon Brown move out of Downing Street and David Cameron move in. I joined the crush by the Downing Street gates (left), having missed the Browns and their boys walking out by about ten minutes. Mounted police, chanting troops-out demonstrators, TV camera crews every ten yards, the relentless whirr of a helicopter overhead and an incredible, exciting atmosphere. I'm quite missing it.
