As a matter of general practice, it is well established that EU law trumps UK national law. I am not saying anything controversial there. As to the particular circumstances here, the answer is that I might well pronounce upon it but I would be extremely foolish to do so off the top of my head. I may be able to sate the curiosity of the hon. Lady, which will be widely shared across the House, but I am afraid that it is not within my gift to do so now. It is better to give a valid and informative answer later than to give an invalid, uninformative and potentially misleading answer now.
