I know that the hon. Gentleman has raised this point under various legislation, such as the Water Act 2003, so he will be aware that the problem of overlap of responsibility on border areas can be resolved through concordats and direct negotiation with the Welsh Assembly. Over the years, we have established a good, effective working relationship with the Welsh Assembly; we are always careful to involve them and to ensure that they are heard in the development of policy strategies and legislation. Together, we have been successful in clarifying the   most appropriate way of dealing with those occasional areas about which there has been an element of doubt.
