Anti-war protesters led by comedian Mark Thomas have heaped fertiliser on the steps of the Labour Party headquarters.
Bemused passers-by looked on as seven sacks of dung were spread near the door of the party offices in Old Queen Street, Westminster, in a protest against conflict in Iraq.
Mr Thomas told a camera crew at the scene: "This is what the people of Britain think of the second UN resolution, which despite the Government's claims, does not specifically call for war on Iraq."
The comedian, who has been involved in a number of protests in the past, left shortly afterwards with the rest of the group after police arrived at the scene.
On top of the heap of dung they left anti-war white ribbons and signs on posts stuck into the pile saying: "US/UK 2nd Resolution" and "Blair-Bush 2nd Resolution" over the picture of a cow.
