HC Deb 20 May 1960 vol 623 cc145-6W
Captain Kerby

asked the Civil Lord of the Admiralty (1) on what date a United States nuclear submarine is due to berth in a United Kingdom port, under arrangements made with him, to commence trials as a guinea-pig for tests with radioactive markers in connection with the positioning of Polaris missile-carrying submarines in British territorial waters;

(2) what steps he is taking to notify Trinity House of the exact positions of the radioactive marker-buys which are to be laid in United Kingdom territorial waters, under arrangements made by Her Majesty's Government, for use by United States Polaris-carrying nuclear submarines, in view of their potential danger to navigation.

Mr. C. Ian Orr-Ewing

No such arrangements have been made with the Admiralty or Her Majesty's Government.
