FORMER US president Donald Trump was due in court today to face another legal challenge, following his record-breaking win in the Iowa caucuses.

Mr Trump was set to face trial to determine how much more he owes the writer E Jean Carroll for denying that he had sexually assaulted her in the 1990s and accusing her of lying when she made her allegations.

In May, a different court awarded Ms Carroll $5 million (around £3.9m) after concluding that Mr Trump had sexually abused her in a department store dressing room in the spring of 1996, then defamed her in 2022 by claiming that she had made the incident up after she revealed it publicly in a 2019 memoir. 

The jury said Ms Carroll had not proved that the former president raped her.

One issue not settled in the first trial was how much Mr Trump owed for comments he made about Ms Carroll while he was still president. That decision will be made by the jury in the lastest trial, which is expected to last several days. 

By winning the Iowa caucuses with a roughly 30 percentage point lead over his nearest rival, Florida governor Ron DeSantis, Mr Trump cemented his position as the favourite to win the Republican presidential nomination.
