The PM sets out the moral case to defeat terrorism and the ideology that feeds isil

As the murders on the streets of Paris reminded us so starkly, Islamic State (Isil) is not some remote problem thousands of miles away; it is a direct threat to our security. So I want the British people to know they have a government that understands the importance of our national security and that we will take whatever actions are necessary to keep our country safe. 

This is not a time to equivocate about allowing our police to shoot a terrorist to save the lives of innocent people. It is not a time to stand back and wish for another world where Jihadi John or Reyaad Khan could somehow be arrested, rather than stopped in their tracks. Neither is it a moment to question our support for our dedicated security and intelligence services, who risk their lives day in and day out – often necessarily without any recognition – in order to keep us safe.
