A New York jury has ordered former president Donald Trump to pay $83.3mn for defaming the writer E Jean Carroll after she accused him of sexual assault, the latest courtroom setback for the former US president who is battling multiple legal cases as he fights to return to the White House.

The verdict, which was handed down on Friday, comes atop the $5mn Trump was ordered to pay Carroll after a separate trial in May, in which a jury found that he had sexually abused, but not raped, her.

The bill could soon grow steeper, with the former president also facing potential damages upwards of $350mn in a separate fraud trial involving his family business, the Trump Organization. A New York judge is expected to issue his judgment before the end of the month.
