I think the reason given was that it was not known and could not be forecast how much it would cost to get it a CoA/into service. Thus both financial and technical.
As with most Govts, money already spent is of no issue to them (except to bash the previous one with) - only how much is this going to cost us? With MRA4, no-one could tell them.
