Government may go to court over future leaks

David Cameron has warned that newspapers may be prevented from publishing sensitive intelligence stories in future, having already caused damage by reporting the Edward Snowden leaks.

But the government may prefer to impose court injunctions on newspapers that publish such stories rather than using the well-established 'D-Notice' advisory system.

D-Notice enables newspaper editors to run stories past the government to check whether they affect national security, although they are not bound by the advice received.

This system has been in force throughout the Guardian's publication of the Snowden leaks but it's not entirely clear that they've stopped any of the reporting.

So if the Prime Minister really wants to get tough, I think he's actually talking about going to the courts more often.
