United States President Donald Trump and Democratic presidential nominee Joe Biden faced off over the US’s record on Covid-19, health care, race, climate crisis, and the economy in a bad-tempered debate marked by insults and repeated interruptions.

Trump, who was expected to try and dominate the first of three such meetings with Biden, repeatedly talked over his rival, and argued with moderator Chris Wallace of Fox News.

Both candidates appeared to flout debate rules in a scrappy head-to-head peppered with insults. Here are the highlights.
