Herewith a guest post from SNP activist Richard Thomson. Richard is a former SNP researcher and Westminster candidate who used to blog at scotsandindependent.blogspot.com. He is now a full-time journalist based in Aberdeenshire.

Since the SNP’s victory in May, Scottish politics had been very quiet. Attribute that to what you will, although the leadership vacuum in the three main opposition parties certainly played a role. However, with this week’s referendum stushie, the brutal truth for Johann Lamont, Ruth Davidson and Willie Rennie is that it’s taken an intervention from the Prime Minister, however ill advised and counterproductive it may have been, to come anywhere close to seizing the political agenda from the SNP.

The PM marched his troops up to the top of the hill last Sunday over setting an 18 month window for holding a referendum. Now, he faces the prospect of having to march them back down again after Alex Salmond revealed what was probably one of the worst kept secrets in Scottish Politics – that there would be a 2014 referendum.

To call for an 18 month timescale on Sunday before running away from that on Monday only to launch a ‘consultation’ on Tuesday is frankly incredible. There’s a book, or at least a series of FOI requests to be written about the twisting and turning going on behind the scenes in Whitehall. There’s nothing like a well-worked strategy and even the most loyal supporter of the Lib/Con coalition would have to concede that this was nothing like a well-worked strategy.

To my mind, Labour, the Conservatives and their Lib Dem partners in government lost the moral authority to set the terms of an independence referendum with the SNP landslide in May. To go from a position of saying ‘no referendum, ever’ to bleating about having one and having it yesterday holds no credibility whatsoever. If a referendum was what was required, then there was ample leverage during the last Scottish Parliament to extract just about any concession on franchise, supervision and timing that could possibly have been desired.

But that chance was spurned and now the SNP is firmly in the driving seat. Forget the misguided talk from Michael Moore about a ‘legally binding’ referendum – there’s can be no such thing in the UK. If the Westminster Government genuinely wants to remove any possibility of grounds for challenge as to the legislative competence of Holyrood to hold a referendum, then it should get on with it, stop trying to attach strings to the vote and accept with as much grace as can be mustered that it has been overtaken by events on this one.

Much of the last week of coalition politicking has left an unpleasant taste in the mouth. Arguments about process, hiding behind the narrowest possible interpretation of the Scotland Act to imply that your opponents have no respect for the rule of law, trying to exert muscle over the what, when and how of people’s ability to voice an opinion on their future governance; none of it is very impressive, far less the sign of a coalition confident in its arguments.

All this rolling around in the mud also highlights, albeit inadvertently, what many in nationalist ranks suspect is the absence of a positive case for the union. This much-vaunted positive case, which must exist somewhere because lots of important people assure us that it does, is always spoken about as if it is a given, yet its elements are never unpacked for examination.

In more wicked moments, I have a vision of there being a strongbox down in the vaults of the Bank of England, embossed with a plate saying ‘Positive Case for Union – open only in Emergency’. Eventually, someone, possibly even Douglas Alexander, decides to blow the dust off and take it upstairs, the better to unleash its power to vanquish ‘narrow nationalism’ once and for all.

“Get out the way! Positive case for Union coming through!”, its bearer will shout. A crowd, hushed with expectation, will gather round, desperate to see for themselves what they have long been told will clinch the debate over their future governance.

After a battle with the lock, the lid creaks open. Then, in the unforgiving light of day, the awful truth emerges – whatever was in there before has turned into little more than a pile of dust. Closer inspection shows a fragment of a picture of what could be a Spitfire, but no-one’s really sure. There’s a bit of what looks like a fragment of a plate from what might be a Royal Wedding, or perhaps even a Coronation. But apart from that and the spiders, there’s nothing – whatever once was there having been eaten away by the ravages of time.

Everyone agrees about the need for a debate on Scotland’s future. Right now, nationalists must feel like Billy Dodds in Tallinn, kicking off while the other team argue about timing and procedural squabbles instead of making sure they are ready to pull on their jerseys and get on with it.

FIFA doesn’t supervise referendum campaigns. If it did, there’d be a strong case for awarding the independence campaign the 3 points now on the grounds of the opposition failing to turn up.
