Kemi Badenoch, James Cleverly, Robert Jenrick and Tom Tugendhat are contenders to become the next Conservative Party leader.     With infighting already playing out among the candidates, and outgoing leader Rishi Sunak calling for party unity, can whoever is successfully chosen last until, and even win, the next general election in 2029?     On this episode of the Sky News Daily, Niall Paterson is at the Tory party conference in Birmingham, and with political editor Beth Rigby, they discuss the leadership hopefuls' campaigns, and the mood among members for their chances against Labour.     Plus, Niall catches up with Conservative MP Iain Duncan Smith, former Tory MPs Penny Mordaunt, Anne-Marie Trevelyan, former special adviser to Boris Johnson Tim Montgomerie, and Conservative commentator Iain Dale.  Producer: Emma Rae Woodhouse Editor: Paul Stanworth
