Clearly you misunderstand the issue of the "West Lothian question"HH. It was never principally about Scot Nats. The problem was policy affecting only England being driven through on the strength of (mainly Labour) Scottish MP's who stood unaffected by those policies. Approving a Queens speech and preventing a power-grab by a party which lost the election most emphatically DOES affect Northern Ireland
The one silver lining in all this is the Sturgeon/Salmond grand ego-trip for Scottish independence is now in shreds for the foreseeable. This may be far more significant long term than the present party-political jostling.
