Joe Biden and Donald Trump will go head to head one last time as the US election campaign reaches its final stretch.

The President's repeated rulebreaking and interrupting of both his rival and the moderator turned the first TV into a chaotic 90 minutes.

And polls suggest Trump's behaviour did him no favours with the public - and Biden's already chunky lead over the incumbent increased yet further.

And when his diagnosis prompted debate organisers to make the second debate virtual, the President declared it a waste of time and pulled out.

After each has had a two minute run at the question, it will be a free-for-all for the remaining time in each segment.

What are the topics for the debate?

In previous elections the final debate has been foreign policy focused - but perhaps in response to the second debate being cancelled, this will not be the case.

The topics for discussion will be:
