Trade (Australia and New Zealand) Bill

Does my right hon. Friend share my concern that the Bill, not just the trade treaty, allows, through the negative procedure, Ministers to change procurement rules? We can say here that the NHS is not for sale and not on the table, and Ministers can say that, but this House does not have a cast-iron guarantee that we would have a vote before any change in procurement rules. An amendment to the Bill to allow that to be done through the positive procedure would be one commitment the Government could give to ensure Parliament gets a cast-iron guarantee.
