I know that the hon. Lady is very concerned about this issue. She will know that the Royal Navy takes its responsibilities very seriously. Since 1993, it has adhered to the comprehensive code of practice and conduct for operations in the vicinity of fishing vessels, which ensures not only the safety of our ships and submarines, but other vessels. I can tell her that any NATO submarine under UK operational control would also have to conform to that code of practice, but obviously we are not responsible for other people’s submarine operations.
