Crowdfunder has raised huge amount within a week
A crowdfunding appeal by Extinction Rebellion is expected to hit £1m after £800,000 was raised in the first week.
The cash is to support its direct action in London with the group saying the cash will be used to fund living expenses of the rebels as they attempt to shut down major infrastructure.
Organisers say that the monthly living expenses amount to £400 for full-time rebels and £200 for part-time ones.
However it is thought the group will not apply for charity status or official funding.
It comes as a UK billionaire worth £1.2billion and rock band Radiohead were revealed among the major donors ploughing money into Extinction Rebellion.
Sir Christopher Hohn, one of the richest men in the UK, has given £50,000 to the environmental group.
Hohn said: “I am a personal funder of Extinction Rebellion.
“I recently gave them £50,000 because humanity is aggressively destroying the world with climate change and there is an urgent need for us all to wake up to this fact.”
The charity he co-founded, the Children’s Investment Fund Foundation (CIFF), is thought to have given a further £150,000 to the climate activist group.
