Does my right hon. Friend agree that the real issue of the events of the last 24 hours is not the party political shenanigans suggested by the shadow Leader of the House, but that this House appears cowed by threats of violence and intimidation? The mother of Parliaments appears weakened and diminished as a result. We have allowed our streets to be dominated by Islamist extremists, and British Jews and others to be too intimidated to walk through central London week after week. Now we are allowing Islamist extremists to intimidate British Members of Parliament. This is wrong. It has to stop. Will my right hon. Friend organise a debate on extremism and how we tackle this challenge, which is one of the central issues facing our generation?
