Last week, I blogged on the problems that Devo Max may pose for Alex Salmond if he decides to include a 2nd question in the coming referendum. However, I managed to miss out one stonker of a problem that I wonder if the SNP has even considered. 

What happens if there are two Yes results and there are significantly more Scots in favour of Devo Max than independence?

The SNP will undoubtedly try to frame the first question of independence as taking priority over the second, much like in 1997, but the two referendums are not really comparable. 

Tax-varying powers was a clear bolt-on to the first question of whether Scotland wants its own Parliament but, as things stand, we will have no means of ascertaining the strength of preference on individual ballots between Devo Max and Independence.

It is safe to assume that those who vote Yes in the first question will also vote Yes in the second but what if a significant bloc, holding at least the casting vote, are really strongly in favour of Devo Max but only in favour of independence on balance? What then?

Of course, the solution to this problem is to have just a straightforward Yes/No on independence or to hold a 3-pronged referendum by STV. 

What is interesting is that the first of these suggestions is building an unlikely alliance ranging from Tom Harris through to Margo MacDonald and including many SNP members along the way, going by Twitter and the Sunday papers.

By charging forwards, Salmond has exposed a chink in the armour and if he has to backpedal to a one question referendum, then this debate really will be winner takes all.    

One thing’s for certain, the debate over what the result means, let alone what the question should be, is only just getting going.Â
