“Rejigging” sounds somewhat shoddy, and I would respect the committee much more than it doing any kind of shoddy workmanship.
All I'm suggesting is that this is a decision truly for parliamentarians, as opposed to the executive. Government has responded to the recommendations made by the commission, and provided that this committee follows the constitutional and statutory principles, it is free to deviate.
I would suggest that the government has considered the proposals very carefully and closely, and I believe they correspond both to the fiscal reality in this country and indeed the constitutional and statutory principles.
