US Election 2024: The Trump v Biden rematch is under way

President Joe Biden and Donald Trump have both swept aside challengers and are all but certain to be the candidates in the US Presidential election in November.

Mr Trump’s last Republican rival, Nikki Haley, has ended her campaign for the nomination after he won overwhelming support in the Super Tuesday primaries. President Biden also swept the board for the Democrat nomination.

The results fire the starting gun for the 2024 campaign proper, a rematch of the last presidential election between the two men in 2020.

It comes as opinion polls suggest that most Americans have reservations about both candidates.
