There are two answers to that question.
First, if you really wanted to know, in terms of the people who set the rules and so on, you'd need to ask people from the House of Commons rather than me. But I think the general answer is lack of transparency. It was a closed system for most of the time, and like any closed system, things happen, ways of doing things develop, so when they come out and are revealed to the public, the public recoils against them. That's essentially what happened. When the public saw some of the claims that were being made, they weren't happy about it. Transparency, though, is the key.
