Jaswant Singh Chail was caught with a loaded crossbow at Windsor Castle on Christmas Day 2021.
A man who arrived at Windsor Castle armed with a crossbow and told a police officer “I am here to kill the Queen” has pleaded guilty to a charge under the Treason Act.
Jaswant Singh Chail, from Hampshire, was arrested on Christmas Day 2021, when the late monarch was living at Windsor due to the Covid pandemic.
At the Old Bailey earlier, Chail, 21, pleaded guilty to three charges.
He is the first person in the UK to be convicted of treason since 1981.
Chail, from North Baddesley, near Southampton, also admitted making threats to kill and possessing the loaded weapon in the castle.
‘Vigilante movie’
He is currently in Broadmoor Hospital, where he appeared in court via a remote video link.
He was spotted by a royal protection officer in a private section of the castle grounds just after 08:10 GMT on 25 December 2021.
The officer was at a gate, leading to the monarch’s private apartments.
Chail had climbed into the grounds using a nylon rope ladder, and had already been there for about two hours.
He was wearing a hood and a mask, and was described as “like something out of a vigilant movie”.
