Going back to past practice, certainly round one typically was for opposition. I put that out there as perhaps a suggestion for a change.
For round three, I see where we have the government, the opposition, and the government. Round four goes to the government and then the opposition. So what you have, in effect, if time permits, is back-to-back government in rounds three and four.
If you're not open to a suggestion of changing round one, which I will leave to you.... You're open...?
