EXTINCTION REBELLION says it will hold one of the country’s largest-ever participatory democratic events in Windsor Great Park.

The environmental activist group outlined plans today for a three-day occupation within sight of Windsor Castle, King Charles’s Berkshire residence, starting this Friday.

The first day will dramatise how Britain’s democratic system has been broken by fossil fuel lobbying with a performance by XR’s black-clad Oil Slicks on the famous vista, the Long Walk.

The occupation’s centrepiece will be a mass assembly “which should be one of the largest participatory democratic events ever held” in Britain on Saturday afternoon, a spokesman said.

Following speeches, participants will be able to deliberate, submit ideas and vote on them online within small groups via the open-source app Polis.

More publicly accessible speeches, training sessions and music will  be held on Sunday morning before a closing performance-action entitled Another World Is Possible.

It will dramatise the death and revival of democracy through theatre, large-scale puppetry and communal song.

Marijn van de Geer of XR’s citizens’ assembly working group said: “Despite vilification from the right-wing media, and new laws putting activists in prison, people are refusing to be silenced and are coming together peacefully to challenge our broken system and to explore together how we can fix it.

“We are defying the current climate of repression — it’s too important not to — we need to be there, we need to be seen and we need to be heard.”

Dr Pete Knapp of Scientists for XR said fossil fuel interests have sown confusion and disinformation about climate science for the past 50 years for profit, while governments “rolled over for these interests, suppressing climate action, imprisoning peaceful protesters and treating the critical threshold of 1.5°C of the Paris Agreement with contempt.”
