Budget Responsibility and National Audit Bill [HL]

We have gone into territory in this discussion that is well beyond the consistency of the Bill. Consistency is important and we of course want to get it right. I see no difficulty in there being an economic forecast, as provided for by Clause 4(3)(a), without there being a government statement in the charter on broader economic policy. I accept that there is a critical need for the OBR to make an economic forecast to underpin its assessment of the fiscal mandate, but I am still struggling to grasp the point on consistency.
