If "Yes" is marked, indicate below the file number assigned to the registrant in connection with Rule 12g3-2(b): Exhibit Index The following document (bearing the exhibit number listed below) is furnished herewith and is made a part of this Report pursuant to the General Instructions for Form 6-K: Exhibit Description No. 1 RNS Announcement, re: 'Application for Injunction' dated 21 September 2004 21 September 2004 British Energy plc Application for injunction against Polygon British Energy announces that today it has made application to the United States District Court, Southern District of New York, for an order against Polygon Investment Partners LLP ("Polygon") and its associates relating to its Schedule 13D filing in respect of British Energy which British Energy considers was filed late and defective because it failed to include material information. The effect of this order if granted would be to require Polygon to refile a Schedule 13D and withdraw its requisition of an Extraordinary General Meeting of British Energy, submitted on 3 September, for a period of time to be determined by the Court. Under US Securities law (which is applicable to British Energy as a company registered with the SEC) any shareholder acquiring an interest in more than 5 per cent. of a registered company with a view to influencing the conduct of that company is obliged to inform the market of that fact under Schedule 13D within 10 days of making such an acquisition. Polygon acquired 35,000,000 ordinary shares in British Energy (representing 5.64 per cent. of the ordinary share capital outstanding) on 23 July 2004. Polygon filed a Schedule 13D notice in respect of this acquisition only on 12 September 2004 more than six weeks after British Energy believes it was required to do so. The effect of the resolutions to be proposed at the EGM requisitioned by Polygon would, if they are passed and nothing else is done, be to prevent British Energy from taking action without which British Energy believes there would be a breach of the binding Creditor Restructuring Agreement entered into by British Energy. In the event of a breach of the CRA and its subsequent termination, the Company would come under an immediate obligation to pay approximately GBP1.5 billion to creditors. The Company has nothing like the available resources to pay these sums. Furthermore the Company may be subject to significant claims for damages from creditors for breach of contract. In these circumstances, there is a very real possibility that British Energy would be forced to commence insolvency proceedings. In these highly unusual circumstances British Energy believes it ought to take every step available to it to avoid these risks and compel compliance with applicable securities laws; hence today's court action.
