Can the Conservative Party manifesto revive Sunak's campaign?

Rishi Sunak has launched the Conservative's election manifesto, promising to slash taxes in a bid to revive the party's floundering campaign.   
  
In his address at the home of the British Grand Prix, the prime minister pledged £17bn in tax cuts including lowering national insurance by 2p, scrapping it entirely for the self-employed and stopping state pensions being taxed with "triple lock plus" - which the party said would all be paid for with £12bn in cuts to the civil service and welfare. 
  
But will it be enough to turn around the fortunes of the Conservatives? 
  
Today on the Daily, Niall Paterson crunches the numbers with Sky's economics and data editor Ed Conway and political communications strategist Jo Tanner unpicks what the Tories are trying to do with this manifesto. Plus, Sky News' political correspondent Darren McCaffrey on if it will shift the dial for the election.
