The clause is needed to allow us to amend schedule 19 in the way that I have just described, and we intend to amend it. We have published what the general duty will involve, with the intention of extending the reach of schedule 19 to other bodies that we think should be in it, but we did not feel that it was right to do that until we had finalised the general duty. Now that duty is in the public domain we can enter into those conversations, but we need a power to add provisions, as necessary, to the schedule.
