Salmond has made it impossible for a CU by demanding one, it would make Westminister look extremely silly if they accepted one. All the Westminister parties have said there will be no CU. The Tories want to stay in power, and the rUK public do not want a CU with an independent Scotland. It would be electoral suicide for the Tories or Labour to enter into a CU, they would have no chance at the next general election.
It's clear as day that there will not be a CU. Salmond knows this, hence why he played the "it's our pound, we're keeping it" card at the last debate with Darling. He has deliberately blurred the lines between a CU and Sterlingisation in order to win votes. Nationalism preys on the gullible (I'm not for one minute suggesting you are gullible by the way).
And why the hard-on for a CU anyway? It's not independence.
Expect nothing from Westminister after a Yes vote, they'll wash their hands as the public in rUK will demand it.
As for an EU referendum I can't lose any sleep about it as membership definitely has its pros and cons, but I'd like to think when push comes to shove that any referendum would show that there are slightly more pros than cons.
