From the site:
This blog will gather examples of defaced Tory Party posters in the run-up to the UK general election 2010.
We will also offer a prize – of an evening’s fine dining with special guests Norman Tebbit and Benjamin Zephaniah, to the creator of the best re-edit of the Tories “I’ve never voted Tory” video campaign.
The reason is simple. We don’t plan on voting Tory, ever. And we’d like to show how many of us think the same way.
