My hon. Friend is right, and of course that is what this Government have done. We have looked at the balance between people’s privacy and liberty and the need for our services to have the appropriate powers and capabilities to keep people safe. I believe that we have struck the right balance, but of course we must continue to consider the issue as matters develop and as the terrorists find new ways of communicating and of carrying out their terrible and horrific attacks. We must be ever vigilant on this matter and that is exactly what the Government have been.
