I understand the noble Lord’s impatience, and commend him for the regularity with which he has addressed this issue. Ministers have made it absolutely clear that doing nothing is not an option. Two weeks ago, there was a workshop of the Cabinet Office, the Home Office and the police to identify more accurately the precise specifications of the scheme that the noble Lord refers to. Later this year, the Environment Agency will be launching a trial scheme using cell broadcasting, and testing the 4G technology to compare it with existing alerting capabilities. The previous trials in 2013 which the noble Lord referred to, were disappointing, but they were based on older technology and the 2G network. Since then, things have moved on.
Finally, the noble Lord referred to the cyclone in India. Most of the existing schemes are used to warn people of tsunamis, flooding and fires. His report used it against a background of terrorism. That raises different issues, in that it is impossible to forecast exactly what is going to happen, and also, in the case of terrorism, the protagonists are also receiving the message alerts. That means that one requires a slightly different approach if one is to use it for those purposes rather than the purposes it is normally used for abroad.
