I think, again, that political culture will be so important. Transition will take time, but yes, the idea of regional MPs from different parties working together is real in Germany, for example, although they have less of a service culture when it comes to their constituents than we do, so it is not tested the same way. Nothing precludes a very different way of interacting professionally as parliamentarians.
