Defence review: ‘War ready’ – but for what war?

The prime minister has launched a 10-year Strategic Defence Review setting out how Britain will operate in an ever-more worrying geopolitical environment. 
 
Sir Keir Starmer says "every citizen has a role to play" in "defence of the realm", but do we know what kind of war we’re preparing for?  
 
On today’s Sky News Daily, Niall Paterson is joined by Sky’s defence editor Deborah Haynes and military analyst Michael Clarke to discuss whether the defence review meets the mark.
