Extinction Rebellion has begun several days of protest in central London as the climate activist group attempts to abandon disruptive tactics and focus on "relationships over roadblocks".
Groups of protesters chanted and danced outside Government departments in Westminster on Friday as they called for more action to tackle the climate crisis.
More than 30,000 people have said they will attend the protests, branded "The Big One", between April 21 and April 24, in what will be XR's first major action since announcing it would move away from more controversial methods of protest and "prioritise attendance over arrest and relationships over roadblocks".
