I am grateful to the hon. Gentleman for his opening remarks. I repeat that the officials and the councillors of Shetland Islands council, both groups of whom I met on Saturday, are working very effectively to deal with this difficult incident. They are getting as much co-operation and assistance as is possible from officials in my Department, in particular the director of the environmental health unit, Dr. Forbes, has been to the islands, as has the chief scientist of SNH. Contacts are continuing at all levels between those groups. Some 20 or more officials from my Department are on the islands fulfilling various tasks and I intend to ensure that that co-operation is maintained for as long as is necessary.
