"People expect MPs to serve the public," said Paul Williamson, 33. "Not to get the most they can out of the job. How can you have any confidence when you have the Commons accounts office saying that it isn't its business to police the system. People used to go into politics to do good. Even if you didn't agree with them, you believed that. But now you have the sense that many of them see it as a good earner, and it's no wonder that people have lost confidence. I've always voted Labour, but next time it will be the Greens. I think this will be an opportunity for smaller parties and that should be good for democracy."
