On Tuesday 23 February 2010, Newsnight will broadcast a special programme debating the main issues facing the future of British defence and security.
We will be asking crucial defence questions - can the war in Afghanistan be won, and when will British troops there return home?
We will take a look at the strategic defence review Green Paper, and consider what resources will be needed to combat future security threats.
Joining Jeremy Paxman will be Secretary of State for Defence, Bob Ainsworth, Shadow Defence Secretary, Liam Fox, and Liberal Democrat defence spokesperson Nick Harvey.
A studio audience will also be taking part in the discussion, comprised of key defence experts and opinion formers, and British soldiers including General Sir Richard Dannatt.
Relatives who have lost loved ones in Afghanistan will also be joining us.
Watch the programme on Tuesday 23 February 2010 at 10.30pm on BBC Two.
