I am sorry, Mr Deputy Speaker. I accept this is a slightly odd way to conduct a debate, but it seems to me to be productive, so bear with us.
There could of course be a general duty to have regard to sustainable development instead of all the duties on all the regulators—we could say that we do not need any other duties—but all the other regulators have lots of other duties, and by introducing economic growth not as an override but as a balancing consideration, that precisely induces them to consider the totality, namely sustainable development.
