Sian Berry will be the Green Party candidate to challenge Sadiq Khan in the 2020 London mayoral elections, it was announced today.
Ms Berry, a Camden councillor and London Assembly member, came third in the 2016 race.
She will make land use central to her campaign, pledging to create a “people’s land bank”.
She said: “The Green Party is the only party Londoners can trust to deliver on its promises.”
She also said that planning the homes London needs should be put in the hands of Londoners.
Ms Berry said in a speech to supporters on Thursday: “The Green Party has a proud history of getting results for London. When we make Londoners a promise, we deliver, and have made real changes even when we are not Mayor.
“In 2016 we promised to give power to residents whose homes faced demolition, and we delivered on that promise. Now we pledge to give Londoners a say on land use in their city.
“London Greens listen to what Londoners need and we act on it. That’s why we believe everyone in London should have an affordable, secure and warm home."
She added: "A Green Mayor would give Londoners control over how our city develops to provide the homes we need with a People’s Land Bank, which would empower communities to find land and buildings currently going to waste and choose how to bring it back into use.
“The Green Party has the answers to London’s biggest problems and we’re the only party Londoners can trust to deliver on its promises.”
Ms Berry joins the race alongside Conservative challenger Shaun Bailey.
The former special advisor to David Cameron was announced as the Tory candidate last September.
A poll in December showed a commanding lead for Mr Khan over Mr Bailey in the 2020 election.
The poll showed Mr Khan's position had improved despite serious political crises over knife crime, slow housing delivery and costly delays to Crossrail.
