Thank you. It's just on this point: you've set out that these costs would happen whether we take the Westminster route or this route. There are administrative costs for the Welsh Government in preparing for what people have voted for, so that's fine, but have you been able to ascertain at all whether the option in this Bill is actually a more expensive option or a different costed option to that that would arise from the EU withdrawal Bill? And in terms of—I'm sure the Conservatives want to save public money, would it not be more appropriate, therefore, for the cheapest and most effective option using public resources to be followed in all cases?
