Does David Cameron know the names of any other SNP MPs? His "belief" that the "senior SNP source" is Alex Salmond has all the significance of gossip. Not that it matters who the source was. Whether it was Salmond or anyone else they were not contradicting the SNP's position but merely indulging some speculation about how things might pan out regardless of that position. There is no great revelation here. Anybody who has any understanding of the situation must realise that a consultative referendum was an option before if the UK Government refused a Section 30 order, and it obviously remains an option should they do so in future. Other points made by this "senior SNP source" are equally valid and uncontroversial. It is an irrefutable fact that the Edinburgh Agreement acknowledged Scotland's right of self-determination. The British state may insist that they didn't really mean it, but the precedent exists. The unionist media are frantically trying to spin two equally false and misleading lines here. Firstly, the idea of dissent and division in the SNP. Particularly between Alex Salmond and Nicola Sturgeon. Secondly, the idea that the SNP is intent on reneging on an undertaking regarding a second referendum. This is doubly dishonest in that there never was any undertaking to put off a referendum indefinitely and regardless of either public demand or altered circumstances. And the SNP leadership has remained steadfastly true to its its declaration that the election result would not constitute a mandate for either independence or a second referendum. But that does not mean that there cannot be another referendum prompted by events or changes in circumstances other than the election result. And, of course, there is the customary hypocrisy in Cameron insisting that his minimal election win gives him an unchallengeable mandate to pursue Tory policies while dismissing the SNP's stunning victory as if it changes nothing.
