I can’t help but think Scotland and Wales are having a political peeing contest just to show who is in charge. With open borders in both and English airports on the borders it is non sensical to vary policy.
imo at times of national crisis and whilst they remain part of the UK,Westminster should have primacy to avoid all this confusion.
there are so many travel & aviation jobs at stake, now is not the time for needless and as I say, in practice ineffective political point scoring.
its a bit like having a customs allowance between England/Scotland and Wales - totally unenforceable and pointless without a hard border.
