While Nick Walker was busy driving around all over London last night, projecting his artwork onto famous British landmarks, Banksy was sitting back enjoying that he was not to be out done, as he effectively stole any and all UK thunder with his newest piece: a gigantic piece of street art, his largest to date, on a wall right next to the CCTV cameras he was mocking. By using scaffolding and passing as workers, Banksy somehow successfully pulled the whole stunt off, thus further securing his legacy and making all other street artist curse his name with big grins on their faces.

Yesterday the scaffolding gang returned to remove all evidence - again without the camera operator stopping them.

The work, above a Post Office yard in Newman Street near Oxford Circus, shows a small boy, watched by a security guard, painting the words: 'One nation under CCTV.'

Andrew Newman, 35, a businessman from Dulwich, who works locally, said: 'It was only on Sunday morning that the Post Offices guys realised what had happened.'
