I cant help thinking if you really were concerned about political corruption you would be having a field day about the Tories rather than the SNP, but I suppose it takes all sorts.
All poltical parties/politicians are corrupt in my view. However all political parties aren’t intent on breaking the union up. In the unlikely event the SNP will ever suceed in doing so, Scotland will go bark to the dark ages, ( @Mike 700 did a good post on this) As for the rest of the union, it will reform as it did in 1922- England, Wales and Northern Ireland, with the union recovering from the shock at a mucher faster pace, than Scotland would ever do.
However this thread is not about the Tories or any other party but, the SNP!
