§ 28. Sir B. Jannerasked the Secretary of State for the Home Department whether he is aware of the development of the laser listener devices which can pick up from windows at a considerable distance conversations which are taking place within the room concerned; and whether he will take steps to protect the security of Government offices against such devices.
§ Mr. Elystan MorganI am aware of the development of these devices. My right hon. Friend has no general responsibility for the security of Government offices, but I can say that due account is taken of this technique where necessary.
