HC Deb 16 July 1981 vol 8 c467W
Mr. Cook.

asked the Secretary of State for Defence whether the United Kingdom is carrying out any research into the compression of plutonium for use in weapons; and if he will make a statement.

Mr. Pattie

The United Kingdom carries out a wide range of research relating to nuclear weapon technology but it has been the practice of successive Governments not to divulge details.
