More than 100 cyclists have ridden around London naked in a mass protest against dependency on the oil industry.
Protesters on The World Naked Bike Ride cycled past Piccadilly Circus, Big Ben, Covent Garden, Oxford Street and the US Embassy on the 10km route.
Riders in 54 cities were protesting at the "destructive effects of car culture" and celebrating "the power and individuality of their bodies".
The ride ended at the Serpentine in Hyde Park.
Rider Melissa Evans, 32, said: "This shows how serious we are in opposing oil dependency.
"Like many people, I'm afraid of showing my body in public, but I'm more afraid of relying on environmentally-destructive fuels."
The event is part of London Sustainability Week 2005 and National Bike Week 2005.
