Northern Ireland Economy

Does the hon. Gentleman agree that perhaps one reason why there was not unanimity was because there was a cloud of judgment over exactly what the Treasury is asking for in terms of costs? It is essential that we get absolute top-desk clarity from the Treasury on what the measure is going to cost; we need to be clear about how it is going to make that calculation. It is important that it takes on board the fact that Northern Ireland will have increased income tax and increased national insurance contributions so as to make the cost less for us as an Executive.
