I think that the Committee wants to implement the spirit and the letter of Smith, and I look forward to hearing the Secretary of State’s response to the detailed arguments advanced by the hon. Member for Banff and Buchan (Dr Whiteford). I think, however, that when we are dealing with a matter as potentially wide-ranging as universal credit, we also need to think about the money, and about how far it is possible to operate a very different welfare system in different parts of a country such as the United Kingdom. What we have seen in the unfolding and dreadful Greek crisis is that, if a country belongs to a currency union but has not brought its benefits system into line, and if there is no proper system of sharing revenues and expenditures throughout the eurozone, that becomes extremely damaging, as it has for the poor Greeks.
