Donald Trump celebrated his victory in the New Hampshire Republican presidential primary on Tuesday night by mocking his last remaining opponent Nikki Haley, complaining about her refusal to drop out as his grip on the party grows ever stronger.

       Mr Trump also appeared to threaten his former UN ambassador, saying that she will end up under investigation for “stuff she doesn’t want to talk about”.

       Meanwhile, the former president has lost his latest appeal against the gag order imposed on him by Judge Tanya Chutkan in the federal election interference case brought against him by Justice Department special counsel Jack Smith.

       A three-judge panel had previously upheld the order, which forbids him from talking about witnesses and court staff.

       Eleven judges from the DC Circuit Court of Appeal have now declined to re-examine the matter but Mr Trump could yet haul it before the Supreme Court.

       The Republican’s defamation trial in New York is currently set to resume on Thursday after Monday’s instalment had to be postponed over concerns about exposure to Covid-19 in both the jury and the defence team, thwarting Mr Trump’s plans to testify against complainant E Jean Carroll, whom he denies sexually assaulting.
