Prosecutors in New York have told the state's supreme court that they would agree to a delay in the sentencing of President-elect Donald Trump for his hush money conviction, but they oppose any attempt by Trump's team to get the case dismissed.

In May, Trump became the first-ever former US president to be convicted of a crime when he was found guilty of falsifying business records to cover-up hush money paid to an adult film star.

But his sentencing has been repeatedly delayed for reasons that included the possible impact on his presidential election campaign. Trump's defense lawyers have requested the case be thrown out.

On Tuesday, District Attorney Alvin Bragg sent a letter to State Supreme Court Justice Juan Merchan to convey the prosecution's decision.

The letter said the prosecutors "are mindful of the demands and obligation of the presidency," but they "also deeply respect the fundamental role of the jury" in the US constitutional system.

Prosecutors also referred to "the need to balance competing constitutional interests."

The state supreme court has not responded to the letter. But US media are speculating that the sentencing, scheduled for next Tuesday, is likely to be delayed further and possibly until after Trump has completed his new term.
