Who else is going to vote for a Party leader if not the Party members in some shape or form Siderite?
It used to be the MPs, along with the unions for Labour. Some might say this isn’t representative, but is the current system, which has 0.1% of the population decide on the leader? Also, at least with MPs they can siphon out the incompetents through experience from working with them.
Electoral reform is something I am warming more and more to, but if we have the current system, as a parliamentary democracy, I am not keen on members having the final say.
