Counter-Terrorism Bill

I am coming to the detail about the amendments, to show that we have been willing to go further to provide the reassurance that colleagues in all parts of the House have sought. In response to my hon. Friend, first, we are clearer in the Bill about the trigger for any use of the power. The power could be brought into force only where it is needed for investigating serious terrorist offences arising out of a grave and exceptional terrorist threat. People have asked what that means. We know that people have plotted to devastate our transport system, to blow up Bluewater shopping centre and, as I said, to use a dirty bomb. We have also seen plots to ensure multiple atrocities. We have seen plots on an international scale that would have brought death on a considerable scale to British people.
