It rests with the Prime Minister. David clearly said it. If the Prime Minister doesn't care about this, none of this matters, and the fact is that none of them have cared about this, and that's why this doesn't happen. I say in my book that, unless a Prime Minister directs it to be done, it won't be done.
I'm not in favour, frankly, of committees and secretariats, because that just diffuses accountability. I like to be able to say, “You're in charge. If it screws up, you're responsible. If it's successful, great for you.” Every time you have these overlaps and duplications, it muddies accountability, and it delays the process.
