Anonymous posters with slogan Strong and stable my arse. were seen across London this week and credited to award-winning artist Jeremy Deller following his interview with The Guardian. Known for creating provocative works of art, these were in response to the Conservative Election campaign.
Update: We even spotted a couple of tribute posters - same slogal, different font. One was stuck to a bin outside a newsagents and one pinned to a bus-stop, in a sleepy Surrey village. They didn't last for long.
