London Assembly and Mayor of London Elections 2020

This election is held under a fair voting system so every vote counts, which makes it one of the most important election campaigns the Greens can fight.  

In the London Assembly now, our two hard-working Greens, Caroline Russell and Siân Berry, are showing the difference that Greens in the room can make. They have: 

  • Secured a ballot for estate residents whose homes are threatened with demolition.
  • Persuaded the Mayor to back a People’s Vote on the final Brexit deal. 
  • Secured 45 million pounds for youth services where money had been cut. 
  • Got the current Mayor to declare emergency action on climate change by 2030
  • Campaigned for rent controls to the point where they now appear to be a central plank of the current Mayor's 2020 manifesto.

Our Mayor of London candidate 2020

Sian Berry

The Mayor of London is elected using the Supplementary Vote system. You make a first and second choice when you vote.

Siân Berry is our Green Party Mayoral candidate.  As a London Assembly Member she has worked tirelessly to fulfil the promises made to Londoners since her election to the London Assembly in 2016.

Our Londonwide Assembly candidates

London Assembly members are elected using the Additional Member system. You vote once for your constituency member and once for a London-wide representative.

We have a strong and diverse team of people ready to represent Londoners on the Assembly where the number of Green candidates elected will be proportional to the number of Green votes we get.  Here, in order of preference, are the candidates we have selected in addition to Siân who is number one on our list.

London she understands the importance of education in providing the skills and confidence our young people need to succeed and will lobby for increased funding for young people’s mental health and for London’s high exclusion rates to be addressed.  Housing is also a priority for Rosamund and she believes that a new target of 50% social housing in each new large development should be set.

Scott Ainslee

 9. Scott Ainslie

In 2014 Scott was elected as the sole Green councillor in Lambeth and spent the next four years facing down a ruling neoliberal Labour Party as they sought to demolish council estates and turn libraries into gyms. He was re-elected to Lambeth Council along with four fellow Greens in 2018 and in early 2019 Lambeth became the first Council to declare a Climate Emergency.  Scott continues the fight for Climate Action, Clean Air and Londoners’ right to a safe, secure and affordable home.
