Trump v Clinton: Complete guide to the final US presidential debate

Trump and Clinton are set to clash for one final time - and the last topic on the agenda could set off the fireworks.

The second US election debate had it all — jail threats, bizarre pre-debate press conferences and an uncomfortable stage format that had Donald Trump looming behind his rival Hillary Clinton. Just how low will it go when Trump and Clinton face off for the final time before America goes to the polls?

Here’s everything you need to know about the third US Election Debate.

When does it take place?

The debate starts at 12pm AEDT today and is scheduled to last for 90 minutes. It takes place at the University of Las Vegas in Nevada.

What is the format?

Exactly the same as the first debate. So no town hall-style questions from the floor this time. The moderator selects the questions and, as always, the candidates are not informed of the question beforehand.

What will we be talking about?

The debate will comprise of six 15-minute segments, each covering a different topic. On the agenda, according to the Commission on Presidential Debates, is Debt and Entitlements, Immigration, Economy, Supreme Court, Foreign Hot Spots and Fitness to be President — potentially setting up a headline-grabbing finale.

Expect an ‘unshackled’ Trump to be quizzed on further allegations of sexual misconduct while Clinton will face tough questions regarding the continuing WikiLeaks revelations.

Who is moderating?

Chris Wallace of Fox News is your man. Wallace is the anchor of Fox News Sunday and the sole moderator fo the final debate. This is the first time a Fox News anchor has moderated a presidential debate and he admitted: “There’s a lot of pressure. There’s a lot of stress. We’ve seen the previous moderators get criticised. And at certain points, I’ve had to remind myself this may be a once in a life opportunity. So have fun.”

What have the candidates been saying?

In Hillary Clinton’s case, not too much. Her team says she is busy preparing for the final debate, but there is also the suggestion she is happy to let Trump’s attacks — and the allegations against him — take the spotlight, while letting the WikiLeaks stories bubble under the radar.

Trump continues his offensive against a ‘rigged election’ and today told voters to ignore mainstream news outlets and instead “read the internet.”

Both remain prolific on Twitter, though, of course ...

• Media is burying new details on Hillary Clinton’s record: Even if average voters had the TV on 24/7, they still probably haven’t heard the news about Hillary Clinton: That the nation now has proof of pretty much everything she has been accused of, writes Kimberley A. Strassel.

• Trump exposes loss of American virtue: Despite all flawed past prophecies it is surely impossible to view the ghastly freak show of the US presidential election without apprehension that we are witnessing the decline of a civilisation and the death of the virtues that made America great, writes Paul Kelly.
