If I had been in front of the committee some years ago, I would have felt obliged to answer that question.
I think I should limit my response to two points. One is to say that the current budget is a two-year framework. In terms of our responsibilities, for practical purposes, we seek the balance in terms of spending authority for one year; we inform Parliament through the reports on plans and priorities of the plans for three years.
Of course, if one looks from one set of RPPs to those that come 12 months later, in respect of year two and then year one, the plans will change, because a variety of things change. The challenge for any part of government, central agency planning or informing Parliament, is to provide both a perspective and a reliable action period.
