The topics have been announced for the final presidential debate between US President Donald Trump and Democratic White House hopeful Joe Biden.

The matchup, moderated by NBC News’ Kristen Welker, is set to take place in Nashville, Tennessee on 22 October. The event will witness the two rivals spar over issues of race relations, climate change, COVID-19, and others, according to the Commission on Presidential Debates.

Questions may also be asked on such topics as national security, leadership and American families, according to a commission news release.

It was added that topics for the presidential debate are typically subject to change, depending on the more recent news cycle in the days leading up to the event.

The format is to be similar to that of the first debate, with every segment lasting about 15 minutes. The candidates will have two minutes to respond after the moderator opens each segment with a question.

The remaining time in the segment will be used by the moderator to encourage further discussion on the topics.

The Commission on Presidential Debates (CPD) did not explain any rule changes for the final matchup, although after the first event it stated on September 30 that additional “structure” needed to be added to the format of remaining debates to “ensure a more orderly discussion of the issues”.

The first face-off between Trump and Biden on September 29 was widely criticized by the US public for being disorderly after the Fox News host and moderator Chris Wallace seemingly failed to take control of the event.
