The bit your wrote about big business and politics is correct. It is well known the large MNC's (multi-national corporations ) make often large political donations in certain democratic countries. Same with the large national companies in those countries.

My point is that in a place like UK or Australia a political party does not get elected unless enough people vote for them.
However, having said that, there are people who say that a voting system based upon preferences is wrong and a perversion of democracy.

So if a voting system is to be fair and proper, preferential votes should be abolished. People should only be able to put 1 in one box only.

I agree with you about Blair, and I don't like a two-party political system either. It's like in Australia also, Liberal and Labor.

There are other parties to vote for however.
