I can assure the right hon. Gentleman that the issue of closed groups on social media—the more private groups—is being taken seriously, and is being looked at. He also asked about intelligence. As he will know, the gathering of intelligence on potential terrorist activities is led by Counter Terrorism Policing, a national policing command working with police forces across the country, together with the domestic Security Service. Its budget has been increased significantly over the last three to four years, and it remains an absolute priority to ensure that it has all the resources that it needs to gather that intelligence.
