Donald Trump en route to New York ahead of arraignment

Donald Trump is flying from his estate in Florida to New York ahead of his scheduled court hearing on Tuesday.

The former US president faces charges relating to hush-money payments made to a porn star before the 2016 election.

Police erected barricades outside Trump Tower over the weekend, with demonstrations expected both there and at the courthouse in Lower Manhattan.

Mr Trump, 76, is expected to arrive on Monday evening and will spend the night in Manhattan.

The exact charges he faces are not yet known but they will be read in full when he appears at the Manhattan Criminal Courts Building at around 14:15 (19:15 BST) on Tuesday.

Some reports suggest the indictment includes around 30 charges related to a $130,000 (£105,000) pay-out to adult film star Stormy Daniels that was made in an attempt to buy her silence over an alleged affair in 2006. The pay-out was made just before the 2016 presidential election, which Mr Trump won over Hillary Clinton.

Two people familiar with the matter told the Associated Press Mr Trump is facing multiple charges of falsifying business records - including at least one felony offence, which would be a more a serious charge.

"On Tuesday morning I will be going to, believe it or not, the Courthouse," he wrote on his Truth Social platform on Sunday. "America was not supposed to be this way!"

The former president is being escorted by members of the US Secret Service and will reportedly fly to New York's LaGuardia Airport aboard his personal plane.

After spending the night in Trump Tower, where extra security measures have been put in place, he will travel to the courthouse with a large Secret Service detail and surrender voluntarily. He is not expected to be handcuffed.

The former president will be fingerprinted as standard arrest procedure, and investigators will complete the usual paperwork and check for outstanding warrants. It remains unclear, however, whether he will be photographed - and provide a mugshot - before the hearing.

He will appear before a judge, who will read the indictment - the set of charges - to him. His lawyers have already said he will plead not guilty.

A group of news organisations, including the New York Times and the Associated Press, have asked that cameras be allowed into the courtroom during the hearing. They have also asked the judge to unseal the indictment and make it public due to the "overwhelming public interest".

Mr Trump's personal plane is on standby for his midday departure from West Palm Beach

Mr Trump is expected to be released on bail and will return to his Florida home, Mar-a-Lago, on Tuesday evening, where he plans to deliver remarks at 20:15 local time.

He is the first US president in history to be charged with a crime, but has repeatedly denied wrongdoing.

The years-long investigation has been led by Manhattan District Attorney Alvin Bragg, a registered Democrat, who Mr Trump says is leading a "political prosecution" aimed at damaging his run for the presidency in 2024.

"We're ready for this fight. And I look forward to moving this thing along as quickly as possible to exonerate him," one of his lawyers, Joe Tacopina, told ABC News on Sunday.

Mr Trump's prospective court appearance comes as he faces numerous other criminal investigations.

On Monday, the Washington Post reported that federal investigators had gathered new evidence suggesting Mr Trump may have obstructed the investigation into the handling of top secret documents at Mar-a-Lago. Mr Trump denies wrongdoing.
