This is great. Brian Haw's protest has been transformed into art and that art itself forms a fresh protest:
Now former Turner Prize nominee Mark Wallinger has recreated the protestor's camp, and his banners, in the Tate.
The gallery falls within a 1km zone around Parliament in which unauthorised demonstrations are prohibited.
Wallinger has placed his exhibition, called State Britain, half inside and half outside the exclusion zone - which is marked on the floor.
