I'm Sian Berry, a London Assembly Member and the Green candidate for Mayor of London in 2020.

On 7 May 2020 Londoners can elect me and a big new group of Green Assembly Members to City Hall.

Greens have a huge reputation in London for strong opposition, good ideas and getting things done, no matter who is the Mayor, since we were first elected to the London Assembly in 2000.

I have stood for Mayor and Assembly twice before, in 2008 and 2016, winning a record Green vote for Mayor each time.

In 2016 we did better than ever. I won third place and the highest number of second preference votes of any candidate.

Now it's time to vote Green again. This election is different. Winning in 2020 is within our grasp.
