The judge has just mentioned the metal mask Chail was wearing when he was arrested, alongside a crossbow and a rope ladder used to access the grounds of Buckingham Palace.

The Metropolitan Police have released a picture of the mask, which you can see below:

This is not the first day of Chail’s sentencing hearing - it began back in July. Here’s what we learned over the first two days:

• Chail had unsuccessfully tried to join the Army to get close to the Royal Family
• His key motive was to “create a new empire by destroying remnants of the British Empire in the UK”, and he was partly inspired by Star Wars, Prosecutor Alison Morgan KC said
• A video was shown where Chail said he was going to “assassinate Elizabeth, Queen of the Royal Family” as revenge for the 1919 Jallianwala Bagh massacre in India
• He had an “emotional and sexual” relationship with his artificial intelligence “girlfriend” Sarai
• Chail had imaginary friends and heard voices but this started to disappear when he was prescribed medication after being arrested
• But a psychiatrist who treated Chail said he was not struck by any evidence of psychosis

The judge has begun his sentencing remarks, where he will lay out the facts of the case and the reasoning behind his sentencing.

We'll bring you what he has to say here.

Shortly after Jaswant Chail was convicted, the Crown Prosecution Service released a picture of the crossbow he was carrying on the night he was caught in Windsor Castle's grounds.

At the time he was detained the crossbow was loaded.

Chail was found by a royal protection police officer in the grounds of Windsor Castle on Christmas morning 2021.

He was carrying a loaded crossbow and was wearing a sinister-looking face mask. Chail had climbed into the grounds using a nylon rope ladder and had already been there for about two hours when he was found at around 08:10, the court heard previously.

The officer, who was posted at a gate leading to the Royal Family’s private apartments, took out his Taser and asked: "Morning, can I help, mate?"

Chail replied: "I am here to kill the Queen."

The protection officer immediately told Chail to drop the crossbow, get on his knees and put his hands on his head.

He complied and then said again: "I am here to kill the Queen.”

Back on Christmas Day 2021, Jaswant Chail was arrested at Windsor Castle, where Queen Elizabeth II had been staying due to the pandemic.

Chail, 19 at the time, told an armed officer he was there to kill the Queen - this was heard by two soldiers from the Grenadier Guards.

The police investigation later discovered that Chail made the same claim in a video recorded four days earlier, which he sent to people on Snapchat about 10 minutes before his arrest.

In February, he pleaded guilty at the Old Bailey to:

• making threats to kill
• possession of an offensive weapon
• being near to the person of the Queen, wilfully producing a loaded crossbow with intent to use the same to injure the person of her Majesty, contrary to the Treason Act 1842

Justice Hilliard is expected to determine whether Chail should be handed a prison sentence or detained under the Mental Health Act.

Experts have previously disagreed in court over the 21-year-old’s state of mind.

A psychiatrist giving evidence for the prosecution said Chail's actions had been "carefully planned and executed".

Dr Nigel Blackwood said Chail did not have a “fundamental breach with reality” at the time, and had sought to apologise, adding: “If you are in the grip of very powerful psychosis you don't seek to apologise.”

However, a psychiatrist who has treated Chail at Broadmoor Hospital recommended that the judge imposes a hospital order.

Dr Christian Brown told the court Chail’s sense of purpose and his relationship with an artificial intelligence-generated “girlfriend” called Sarai were" really pertinent to his diagnosis of psychosis".

The first person convicted of treason in more than 40 years is due to be sentenced in London’s Old Bailey court soon.

Jaswant Singh Chail, 21, was caught on the grounds of Windsor Castle with a loaded crossbow on Christmas Day 2021.

Wearing a mask, he told a protection officer "I am here to kill the Queen”, was immediately arrested and sectioned, and later pleaded guilty to a charge under the Treason Act.

He also admitted making threats to kill and possessing an offensive weapon.

I’m with Adam Durbin, Thomas Mackintosh and Marcus White, who will be writing the latest from court, and you’ll be able to watch the judge’s remarks live shortly.
