I think, frankly, First Minister, that administrative devolution in this area would be a very meagre thing. Now, since 1945, the social contract that's been the bedrock of the welfare state is that a citizen has a direct relationship with the state for a level of economic security and, no matter where he or she lives in the United Kingdom, they have the same basic economic rights to benefits. If we mess about with this principle, we could end up breaking that consensus we currently enjoy and that sustains a welfare state. We need to be very, very careful about this sort of fragmentation.
