Try explaining the precise nature of Great Britain and Ireland's constitutional arrangements to an interested observer...say an American mudcatter. Where would we start?? I give up.
   This current controversy certainly highlights one of the most amazing things: yes, why can Scottish MPs vote on purely English and Welsh matters, but English and Welsh MPs cant vote on Scottih ones? there must be a reason somewhere, but exactly what that reason is is a little difficult to grasp. (just to be precise by "Scottish MPs" I mean (in this context) members sitting for Scottish constituencies: not Scottish people who are members of the House of Commons, a completely different category!!)
