Will Starmer's 'no pain, no gain' strategy pay off?

As Sir Keir Starmer delivers his first leader's speech as prime minister to a packed-out conference hall in Liverpool, can he convince his party, and the country, that Labour's promise to deliver "national renewal" in return for short-term pain will be worth it?  
  
Niall Paterson gets the reaction of Labour's front bench from the conference floor and sits down with Sky's deputy political editor Sam Coates. They discuss if Sir Keir can convince the public that austerity is not a possibility.
