Thank you, sir. I certainly agree that Parliament must use its powers to scrutinize government expenditures. But returning to your first point, I see there being a large identity in a parliamentary system between the executive and the legislature. Although our Parliament became strong in the Middle Ages in the United Kingdom because it brought the executive under control, it did so at a time when the king was the executive and was outside Parliament. The executive has moved into Parliament and controls Parliament from the inside. That is our system.
I personally don't have any particular problem with that, as long as a government is obliged to present full information to their Parliament and gives parliamentarians sufficient opportunities to consider the proposals they're putting before Parliament. I think that's where your problem, as you've identified it, comes in.
There certainly should be a full opportunity for the parliamentarians to have a good explanation of what the government is intending in terms of adding to expenditures, and a good opportunity to criticize and have before it the ministers and relevant officials so the full explanation takes place. I think there can be improvements to the process that parliaments use to consider estimates, but it's a mistake to think that the parliament should be rewriting and controlling the estimates. I do not see that being a practicable or a constitutionally appropriate parliamentary role in modern times.
There can be improvements to the process, but one must start out with a certain political and constitutional reality from which one works.
