I speak as someone who strongly supports devolution, and I'm really pleased that we've got devolution of powers to the large English cities. But does the Minister agree with me that asymmetric devolution does not work, that the primacy of Westminster means that it can override any Welsh law and also interfere with any Welsh laws, that we need an agreed devolution settlement, with a proper reserved-powers model, as opposed to the reserved-powers model we've got at the moment, which has very little in common with a reserved-powers model, and, finally, that we need devo max?
