Former Chancellor Rishi Sunak convincingly won over an audience of Conservative Party members in a head-to-head television debate with rival Foreign Secretary Liz Truss in the leadership contest to elect a new Tory party leader and British prime minister.

The 'Battle for Number 10' on 'Sky News' on Thursday night brought the finalists face to face with Conservative members who are entitled to vote in the election but are mostly undecided on their choice.
