US President Joe Biden has challenged Donald Trump, his likely main rival in the 2024 election, to two televised debates in the run-up to the polls in November.

Trump was quick to accept the invitation – saying he would debate Biden anytime, any day.

Biden has deviated from the conventional timings, style and organisers.

The date for the first sparring match is so early that neither candidate will have formally accepted their party’s nomination.

And for at least that debate, there will be no live audience.

The two men are already exchanging insults on social media.

So what are the key issues to look out for – if and when they face each other?

And how important are these debates?
