River Tweed (Pollution) Mr. John Home Robertson asked the Solicitor-General for Scotland if he will instruct the procurator-fiscal of Berwick shire to investigate pollution of the Tweed and its tributaries, following the shutdown of sewage treatment works in recent weeks, with a view to possible prosecution of the Borders regional council under the Rivers (Prevention of Pollution) (Scotland) Act 1965. The Solicitor-General for Scotland I have instructed the Procurator-Fiscal at Duns to carry out an investigation and report to me. I shall write to the hon. Member in due course.
