The Prime Minister has just given a strong defence of the plans for 'secret courts' and more internet surveillance.
His main point was that as Prime Minister his responsibility was to keep the country safe and therefore plug significant gaps in national security.
There was a little nod to Nick Clegg's concerns with Mr Cameron, saying he would listen to concerns, and protect civil liberties.
But this was the Prime Minister in essence saying it's his job to take the tough decisions and he will do all he can to protect people.
So it's the Prime Minister's strong law and order message against Mr Clegg's civil liberties one.
