From the formation of the Green Party of England and Wales in 1990 until 2008, the party had elected spokespeople called principal speakers instead of leaders. From 1990 to 1992, the party had six principal speakers and from 1992 to 2008, the party had two principal speakers: one male and one female. In November 2007, the party held an internal referendum on whether they should replace the system of principal speakers with a single leader. The party's female speaker,
Caroline Lucas, supported introducing a single leader, as did the party activists
Tony Juniper and
Jonathon Porritt. The party's male principal speaker,
Derek Wall, opposed the change, as did
Jenny Jones, one of the party's two members of the
London Assembly. The other Assembly Member,
Darren Johnson, ran the campaign in favour of moving to a leadership model. == Campaign ==
