Sian Berry: Has campaigned against 4x4 vehicles

The party's joint leader got 45% of the vote, beating four others hoping to challenge Ken Livingstone next year.

She said the party's vision was "a fairer, greener, healthier London. A city run on a human scale".

In 2004 Green candidate Darren Johnson came seventh with 57,000, or 2.9%, of first preference votes. He got 209,000, or 10.9%, of second preference votes.

Ms Berry said: "Life is a struggle for ordinary people in London. If it's not the chaos of our transport network, it's the high cost of living, the daily struggle to make a living wage, or crazy levels of rent and mortgages.

"Our vision is clear: a fairer, greener, healthier London. A city run on a human scale, which enriches the lives of everyone.

"A Green mayor would be the best thing that ever happened to London. I can help bring a wide range of voters behind us with my record of action, and our vision of London as the world's leading example of a diverse, socially just, green city."

The Green Party in England and Wales does not have an individual leader, it has a male and female principal speaker. Sian Berry was elected unopposed as female principal speaker last September.
