Recent polling figures have shown that with the Conservative Party likely to reduce its allocation on the London Assembly after the election next week, the Greens could help hold the balance of power next term.
Green Party Mayoral candidate Jenny Jones, who along with Darren Johnson, is one of two existing London Assembly members, said: "The Greens have consistently been able to play a leading role in determining policy at City Hall, and by voting Green on the Assembly in May London can help ensure whoever is Mayor next year is best held to account.
"The introduction of civil partnerships and the London Living Wage, the prevention of the Thames Gateway Bridge and massive increases in the cycling budget and provision all demonstrate that the Greens are able to set aside personality politics and old rivalries to win real achievements for Londoners.
"Whatever the results in the Mayoral and Assembly elections, we will use our influence next term to win real victories for Londoners on the issues that affect them most: making fares affordable, tackling the air pollution that claims so many lives, restoring trust in the police and making London fairer and more equal for everyone.
"As I said yesterday, the polls don’t always provide a fair reflection on voting attention-and these aren’t even our best results this week-but we are very happy that more and more Londoners are relating to our Green vision for the capital."
