The hon. Gentleman is absolutely right in the way he has outlined and highlighted this just appalling issue. There is a great deal of work taking place internationally, mainly through our intelligence organisations and agencies, with the shared work they are doing. In fact, last Thursday I had my latest briefing on some of the organisations and groups, and some of the ways in which they connect and share information—open-source activity, as well as on the dark web. As I have already highlighted, and as I said to my hon. Friend Rehman Chishti, I am more than happy to provide further information about the work that has taken place. This is a serious and growing threat, and we have lone actors operating around the world on virtual networks. There is a great deal of work that has taken place that we can be proud of, but at the same time we have to be vigilant to protect our people and our country, and to prevent some terrible atrocity from taking place.
