Watch this space. Danny Alexander is about to speak to the pensions industry in Edinbiurgh where he will say the currency union refusal is final, and agreed between him, Osborn and Balls. Or in other words, anybody who will be at No.11 in the aftermath of the exceedingly slim chance of a yes vote.

Without publishing a plan B, how can the referendum even go ahead? If you vote yes, what are you voting for?

I reckon it is a huge insult to the voters of Scotland to ask them to vote for something that cannot be delivered and would have to go through the expense of a second referendum after Labour are returned in the Scottish election that would follow the vote of no confidence in the government in, I'd say October.

That's assuming The UK agreed to it, and under what conditions.
