In a warning to organisers, the Metropolitan Police charged three supporters of the group on Thursday, who became the first to face such charges. More than 200 protesters have been arrested during marches by Defend Our Juries, who organise the gatherings, since the Palestine Action ban came into force last month.

Two women and a man have been charged with showing support for proscribed terror group Palestine Action following a protest in central London. Jeremy Shippam, 71, of West Sussex, Judit Murray, 71, of Surrey, and Fiona Maclean, 53, of Hackney are due to appear at Westminster Magistrates' Court on 16 September, the Metropolitan Police said.

The U.K. government has proscribed the network as a terrorist group, a decision fiercely contested by the group itself.
