A spokesman said there would be no escalation of activity on Easter Monday, but warned that the disruption could get “much worse” if politicians are not open to their negotiation requests.
The group will no longer hold a picnic on the Westway by Edgware Road Underground station, which would have stopped traffic on the busy A-road on the last day of the long Easter weekend.
Instead, at Marble Arch, the only police-sanctioned protest space, activists will meet to “vision what’s going to happen in the coming week”, an Extinction Rebellion member said, as she introduced Swedish activist Greta Thunberg to the stage.
The 16-year-old was met with cheers as she told a crowd of hundreds that humanity was at a crossroads.
Earlier on Sunday, in what the group later said was an internal memo intended to garner feedback from members, Farhana Yamin, the group’s political circle co-ordinator, said they would shift tactics to “focus on political demands”.
She added: “Being able to ‘pause’ a rebellion shows that we are organised and a long-term political force to be reckoned with.”
