Marine and Coastal Access Bill [HL]

I am grateful to the Minister for giving way. This is an important area, because a lock is for one purpose; to allow water to be retained. However, sluices are very similar structures and the water contained within them would never be considered sea, but it would include all the drainage of the fenland basin. I understand exactly what the Minister means; he knows that, generally speaking, I agree with the Government's definition of where the sea, or the marine area, starts; but I am concerned by the wording of Clause 4. It needs to be quite clear that sea banks, sluices and areas protected from the sea by artificial means are not included within the meaning of the Bill.
