On the contrary, rules apply no matter what party you're in. It's just a matter of shame that reactionaries such as yourself and claig are quick to point out corruption when it comes to 'the other team', but don't take much interest in corruption from your own favourite team.
The fact is, the system itself is broken, and politics is utterly corrupt. Parliament doesn't represent the interests of the public, but of a tiny percent of the wealthiest individuals and large businesses.
The sooner you come to terms with this, the sooner you can stop feigning being by allegations of corruption by whatever team.
