No, if you have looked over the last number of years, any department that decides to spend in advance of receiving the appropriate authority through Parliament does so very much at their own risk, because Parliament can decide at any point in time not to approve that particular spending. That happened, in fact, in the last minority government. I would argue that departments need to be very prudent until they do receive parliamentary approval. That is where, at the end of the day, spending is approved.
