There was a Zombie party running here (one of their policies was universal post mortem rights and suffrage). We also have the Monster Raving Loonies (this year one policy seemed to be the introduction of a 99p coin to prevent pointless small change).
There were also many not so comedy parties who were all single issue crazy. UKIP (the get out of Europe even though it means we get fucked in economic and trade stuff party), the BNP (oh no, we are not at all a racist party but we want all the immigrants given a grant to fuck off back home party), the Christian party and common good parties (who both seemed to be of the opinion that the whole world would be nice if everyone was white, middle class, middle aged and christian) and so on. I even saw a few candidates for the national front who I thought had long ago gone the way of the skinhead and the union jack...
There were a few other crazy parties as well, but I can't remember all the names. Many of them seemed to be running under a platform of 'getting all the potholes in the roads' sorted out...
