Whitewashing £300,000

No Daily Mail: For more than five years, John Travolta and Samuel L Jackson wielded their bananas menacingly by a road junction in Central London. Spray-painted on the side of an electricity substation by the infamous graffiti artist Banksy, the image of the Pulp Fiction stars became world famous.

However, earlier this month a group of Transport for London workers were instructed to spruce up the area - and painted over the Banksy with whitewash. "We have no intention of changing this policy. We recognise that there are those who view Banksy's work as legitimate art, but sadly our graffiti removal teams are staffed by professional cleaners not professional art critics."

A friend of the artist said the Pulp Fiction image would could have fetched £300,000 if it had been bought in situ or relocated. "This piece was the most iconic of all Banksy's work."
