Ellie Chowns (Green MEP for the West Midlands) being led away by police during the Extinction Rebellion protests in London.

Ellie Chowns said on Twitter: “Last night I was arrested in Trafalgar Square while defending the right to peaceful public protest. That right is central to a functioning democracy.

Yesterday, public protest was banned throughout our capital city. This is a completely unjustified and disproportionate measure.”
