Last week the Prime Minister debated questions of security and civil liberties with Observer columnist Henry Porter.
Their exchange prompted a huge response from readers who wrote, emailed and posted comments on our blog, as well as at the bottom of our leader article. If you want to join the debate, don't post here; please continue to post your comments on this blog.
The debate will continue in the pages of the Observer and online and a government figure will respond to the issues raised - we'll keep you informed.
