ECO idiots are plotting to storm Windsor Castle and break into private royal grounds in three days of chaos, according to reports.
Extinction Rebellion activists plan to create a diversion on The Long Walk which would allow members of the group to break into the castle grounds.
In a report seen by MailOnline, the protesters will also try and create mayhem in Windsor town centre by targeting hotels and restaurants and blocking roads.
A leading security and risk assessment organisation infiltrated XR group chats where the mass demonstration was discussed.
The non-violent action, from August 30 to September 1, was also planned during a zoom meeting.
An investigator, who posed as an activist, listened as environmental zealots talked about the demo.
A risk assessment by a local business also revealed XR organisers are encouraging elderly and disabled activists to attend.
The eco rabble previously announced they would stage a mass occupation outside Windsor Castle to protest against the King — even though he is a green campaigner.
Climate activists claimed it is the "embodiment of a broken and unjust system".
Extinction Rebellion says its occupation of Windsor Great Park is to urge the King to do yet more on green issues.
The protest, called Upgrade Democracy, will not specifically target the King or any individual, it claims.
Catherine Bartlett, of Extinction Rebellion UK, said in a rambling press release: "Windsor Castle has been chosen as an embodiment of a broken and unjust system where our message will resonate powerfully.
"The general election has neither fixed our broken system nor addressed the urgent action needed to tackle the climate and nature emergency.
"We demand better at all levels; from the head of state to local councils but our central demand is for a Citizens' Assembly on Climate and Ecological Justice, which is needed more urgently now than ever before."
However Windsor Great Park has been practising sustainable land use for hundreds of years.
