It appears that the SNP has realised that in pure Westminster terms, despite its stunning result at the General Election, it will yield little real power.

To that end, this interview in the FT shows that they are flexing their muscles in a more public and confrontational way.

It is not clear how the Government intends to react to this muscular form of Scottish nationalism and whether they will seek to oppose or compromise. If it is the latter then the SNP will rightly claim a victory. If it is the former then the SNP will have to deliver on its threats.

The role of the Labour Party in all this is unclear and until they have a leader in place that is likely to remain the case. But the SNP in Westminster terms is a minority party, it needs to work with Labour to inflict damage on the Government. What is in it for Labour remains to be seen.
