I am grateful to the hon. Gentleman for carrying out the undertaking which he gave in Committee and also for the way in which he phrased his speech just now. The subsection as amended covers the point that I had in mind. There may be confusion or dispute over a consent if it is not in writing, but if it is in writing there can be no dispute about it and all parties will be bound by it. I repeat that I am grateful to the hon. Gentleman for making this Amendment.
