Re: What a horrible waste of time and money
'It would be a brave new PM indeed who took up the job and said, "er, well, I'm not going to do what you asked, I'm going to do what I want to do, instead."'
It would also be a brave PM who took up the job and said "I'm going to go ahead with what you voted for even though most of you are against it now you've discovered what the consequences will be.".
52% falls well short of what you'd have to consider a "expressed will" for a change of this magnitude. First past the post might be reasonable for putting someone into Parliament to be your MP for a maximum of 5 years. It should take a lot more than that for what would be effectively an irreversible change in constitutional and economic affairs with a massive impact.
