My Lords, I refer to my interest as chair of the National Preparedness Commission. Disruption to cables would have potentially huge effects on communications, data and so on—so too, incidentally, would disruption to the satellite systems on which we all depend. The strategic defence review called for a national conversation about raising the country’s awareness of the threats we face. Is there any plan to have a national exercise, involving large businesses as well as government departments, local authorities and local voluntary organisations, to prepare for a major communications or data disruption?
