How do you stop a politician or minister ruining our country and then migrating to another?

They aren't as much a traitor to their country as they are to the people they are supposed to represent. None of our politicians have represented the people unless its been more to their benefit and they gain something out of it. Mostly money but sometimes political clout and power. Best thing the British can do is to vote out every sitting MP. That would make all who run for office in the future sit up and take notice that democracy can work for the people instead of just for politicians when they want your vote and the pigs trough they all have their noses in. They also would know that the lies, deceit and broken promises would get them voted out and thus lose all the perks they normally get with the job. Do it. Don't be a sheep and listen to the present lots lies. Vote any independent and get them out. We can't get much worse than the way they have made the country now. Even the BNP's jackboot isn't as large as the one they all wear.
