The election follows the party's decision to replace its current system of two Principal Speakers with a single leader. The change was supported by one Principal Speaker, Caroline Lucas, but opposed by the other, Derek Wall. It gained the support of 73% of party members who cast a vote. Caroline Lucas launched a campaign for the Leadership on 14 July. The other candidate for the leadership was Ashley Gunstock, an actor best known for his role in The Bill. Hustings took place at the Green Party of England and Wales' conference, and the results were announced on 5 September at approximately 8pm.
