So in an Alternative Vote System or PR, you dont actually vote for the MP, just the Party.
The Party then has carte blanche to nominate in the order they choose who gets the seat in parliament.
Some democracy that is.
Also coalition governments like in Italy, 42 in 46 years. Now that’s expensive!
You would get fringe parties popping up everywhere, the ballot paper would be a mile long after a couple of elections.
First past the post may not be perfect, but at least you can vote for your local MP and it creates more stable government.
I would prefer to see terms limits for MP’s in the Commons and Lords introduced.
