GREEN Party co-leader Caroline Lucas may be stepping down but will continue to play a valuable role as MP for Brighton Pavilion.

The Greens’ sole MP has long been one of Parliament’s most powerful voices in opposition to the sleaze and entitlement that characterise that institution.

The Greens have become a more prominent force in British politics since she first became leader in 2008 and she has done much to add a radical critique of capitalism and injustice to its traditional focus on environmental issues.
