Very good and very funny; WHY did it take them so long? In response to Labour supporters' joke Tory posters; remember the David Cameron ones? We have a site dedicated to Labour (click on image) and many are hilarious; my favourites are the burglar on sentencing policy and the benefits ones for instance: ENJOY.
Update: just read the graveyard one re postal votes! ROFL!
Update 2 (Friday): more equally funny but non-filtered posters at jontomes place.
