Key moments: Policy over petulance in final US presidential debate

President Donald Trump and Democratic challenger Joe Biden have met for the second and last time on a debate stage after a previously scheduled town hall debate was scrapped when the Republican incumbent became one of the millions of Americans to contract coronavirus.
For Mr Trump, the match-up at Tennessee’s Belmont University was perhaps the final opportunity to change the dynamics of a race dominated, much to his chagrin, by his response to the pandemic and its economic fallout. For Mr Biden, it was 90 minutes to solidify an apparent lead less than two weeks before the election.
