The Group called for a first preference vote for the Green Party candidate, the eco-socialist Siân Berry, in the 2008 London mayoral election.
Incumbent mayor Ken Livingstone, candidate for the Labour Party, formed an electoral pact with the Green Party mayoral candidate Siân Berry via the supplementary voting system, in which Labour voters were encouraged to place the Green candidate as their second preference, and vice versa.
