Militant eco-activists have joined forces with supporters of the banned group Palestine Action, raising fears that Britain could face months of protest chaos.
Eco-warriors from Just Stop Oil (JSO), Extinction Rebellion (XR) and Insulate Britain plan to back Palestine Action supporters during a fraught weekend of demonstrations.
Police are gearing up to make mass arrests on Saturday when more than 500 people are expected to descend on London in solidarity with the outlawed pro-Gaza group.
And 3,000 riot officers will reportedly be deployed and placed on standby to keep the peace at a series of anti-asylum demonstrations and counter protests in locations including Islington and Canary Wharf in London.
JSO activists with a history of vandalising national treasures, blocking motorways and disrupting major sporting events are among those who have been held by police in recent weeks for supporting Palestine Action, which was proscribed as a terror group last month.
