Re the super-majority Steve. That is a non-starter. That is what happened in the first devolution referendum. Those supporting a devolved parliament won but not by a big enough margin as laid down by the UK gvt. That caused a boil to fester which very soon led to a second campaign for devolution to start up. There was deep resentment that a referendum vote had been won but in essence those who didn't vote or were even dead but still on the register were counted as voting against.
