Greater devolution will be the answer as a way of delaying the inevitable. One day there will be a clear mandate to break up the UK, possibly not in my lifetime but that's the way things are heading in my view.
The push may even come from England rather than Scotland, Wales or NI. One thing I was sure of right from the start when the referendum was agreed was that it was a win win situation for the nationalists.
A Federation with a proper Constitution (instead of people picking and choosing what laws they consider constitutional laws as it's convenient for them) is going to be the lasting answer for the UK.
I'm sure that a bunch of Constitutional lawyers from Canada and Australia would be happy to advise the British on how to make it work with the existing monarchy. The Constitution of Australia would be an ideal model to start with as it has the best defined procedure for making changes to the Constitution (including referenda that actually have proper legal force, unlike this one which would have been more correctly called a plebiscite) and there would be the chance to make various improvements (mostly changes to the separation of powers) just as its writers incorporated lessons (both copying the good and discarding the bad) from the Constitutions of Canada and Switzerland.
Fair play to Salmond - he is going to do the honourable thing and fall on his claymore.
What would Salmond know about honour, has he ever served?
Resigning is just a way to avoid being the first casualty in the SNP's inevitable night of the long knives. If he really was as proud with the campaign as he said he was in his concession speech, he would have had the courage of his convictions to stay and keep fighting the good fight.
To lose the referendum by a margin of over 10% is an absolutely massive defeat for any referendum held in a stable country, even more so for a partisan effort being pushed by one political party where proper referenda usually involve politicians of all parties being led to it by the people. I've participated in a couple of important referenda which had proper legal force (as a voter at the 1998 Australian referendum on the republic, and as a polling officer for the South Sudan secession referendum) and which had next to no level of party politics involved, because there was a broad base of support which led to them taking place. This Scotland plebiscite seems to be the complete opposite, with more features common to a normal election - concession speeches, coverage comparing swing against the SNP vote in previous elections, and then the leader standing down after a whopping great defeat.
Most of the SNP and LD seats in Scotland used to be Conservative at one time.
Younger members may not realise the Tories got 33% of the Vote at the 1979 Election and had twenty odd seats in Scotland.
Times change and parties shift, it's a fact of politics.
This fact was conveniently put to one side by the SNP in their fear campaign, with their attempts to get people to vote Yes because staying in the UK would mean being ruled by the Tories after some elections. The Tories won't get the majority of seats in England forever and neither would Scotland seceding consign the UK to a perpetual Tory government, because new leaders would come through from the other parties to take up the fight.
For a more extreme example, Barack Obama (of the Democratic Party) is a more right-wing president of the USA than any president from the Republican Party prior to George Bush. Both parties have shifted way to the right over the last 40-60 years - the Republican Party which obstructs Obama's legislation at the moment was also the same party which had a president (Eisenhower) deploy the 101st Airborne Division to enforce the racial desegregation of Little Rock Central High School against the wishes of the Democratic Party's state governor.
