May I take this opportunity to congratulate my right hon. Friend Sajid Javid on his appointment to the Home Office, which is such an important Department in terms of not only security but ensuring we have a safe and fair immigration policy? The UK threat level remains at severe. Last year we had five terrorist attacks that got through, and 36 innocent people were killed. May I invite the Prime Minister to share our admiration for the extraordinary work and bravery of our counter-terrorism police, our emergency services and our security services, for which I know we are all grateful?
