Dr Julian Lewis: I welcome the fact that the Government have chosen to make this statement [on raising the UK terrorism threat level]. The attack plans of lone terrorists are obviously the hardest to anticipate, yet their behaviour often sends signals to those in their immediate circle. What advice does my right hon. Friend have for people who see worrying signs that someone they know is developing an extremist outlook?

[The Minister for Security (James Brokenshire): My right hon. Friend makes a really important point about the nature of the threat that we face from self-motivated individuals, but they are not isolated and they are not alone; they sit within communities and within families. They have connections with different agencies. That is why we introduced the Prevent duty on statutory agencies, but if people have concerns, they should report them in confidence to the police. The counter-terrorism hotline is 0800 789 321. There are additional resources online at gov.uk and also the Action Counters Terrorism – or ACT – app. That can be downloaded and provides further information and ways to report.]
