Mr. John McKeon:

I can address a couple of points. I have already acknowledged that in retrospect, it would have been preferable to have a single business case document. I agree with the points made in the 2016 document that the project had many of the elements of a business but not all of them. I absolutely agree on that. The Secretary General of the time indicated we would do an estimate of benefits, which have been done and produced for the committee. In light of the concern expressed by the committee about value for money, although it is after the event it is still worthwhile doing a cost-benefit analysis.
