I propose to take Questions Nos. 19, 45, 46 and 56 together.
On 10 July, 14 October and 13 November 1997 I briefed the House on revelations by the UK authorities that radioactive material had been dumped in the Irish Sea and elsewhere around the coast of the United Kingdom in the 1950s, 1960s, and 1970s. An archival search by the UK revealed that dumping had taken place at a number of locations including Beaufort's Dyke, the Holyhead Deep, the Firth of Forth, the North Sea, the Firth of Clyde, and off the Isle of Arran. In addition, a number of instances were identified where liquid wastes containing small amounts of radioactivity were dumped at sea. These instances occurred in the North Sea, the Firth of Forth, Liverpool Bay and, possibly, Morcambe Bay and the Humber Estuary.
