There is an interesting Wiki which was set up last month by Paul Youlten who is also the founder of Yellowikis (a user generated yellow pages on the web).
The stated aim of They Want to Work For You is to create a complete guide to each and every candidate planning to stand for Parliament in the next UK General Election. New media expert Seb Bacon conceived the idea in a blog post at MySociety.org in 2006 inspired by their TheyWorkForYou site. Paul Youlten launched the wiki in May 2009.
At the moment the data is incomplete but it has the potential to be a fascinating crowd sourced database in the run up to the election.
