Leader of the Green Party of England and Wales

At the party's 2007 spring conference in Swansea, members voted to hold a cross-party referendum on whether the posts should be changed to leader and deputy leader (with the option for co-leaders if two candidates chose to run together and were gender balanced, in the event of which there would be no deputy leader). The new system would allow the leader and deputy (or co-leaders) to vote on GPEx and, rather than being elected annually (like the principal speakers), the posts would be elected every two years. Provisions for recalling the leader and deputy were articulated.[3] Despite the controversial nature of this issue, many participants, such as Siân Berry, were struck by the how "constructive" the debate turned out to be.[4]

On Friday 30 November 2007 the ballots were counted and members voted 73% to 27% in favour of the new leadership model, with a 48.3% turnout of Green Party members.[5]

Supporters of the 'Green Yes' campaign for a yes vote in the referendum included the then-principal speaker Caroline Lucas MEP, Siân Berry, Darren Johnson AM (a Green member of the London Assembly), environmental commentator and Green member Mark Lynas, former principal speaker Jonathon Porritt, councillors from Lewisham, Brighton, Norwich, Leicester and Lancaster, and members of the Green Party Executive (GPEx), including Jim Killock (external communications officer), elections coordinator Peter Cranie and Khalid Hussenbux, the party's financial coordinator.[6]

The Green Yes campaign believed that the Green Party needed a leader to reach its potential and that, if the party did not reach its potential, it would be "selling-short our planet and everything on it". They suggested that the party's success has been too slow and that "a leader would help set direction, political focus and make sure the party gets the resources to grow". The campaign hoped that having a Leader would be "about empowering the party" and "about accountability", in that a Leader would "mean we can identify who to hold to account when things need changing". The group added that other Green Parties in the world had leaders and remained "just as Green as the rest of us".[6]

Mark Lynas, in several editions of his New Statesman blog, further claimed that the name 'Principal Speaker' was not transparent to the public, that it wasted valuable time in explaining the system to the media and that it lacked credibility.[7] Darren Johnson characterized the lack of single leader as "just a ridiculous barrier in terms of getting our really important message across".[8]

Supporters of the 'Green Empowerment' campaign for a no vote in the leadership referendum included the then-Principal Speaker Derek Wall, Jenny Jones AM (a Green member of the London Assembly), the late Timothy Beaumont (Green member of the House of Lords), prominent human rights campaigner and Green member Peter Tatchell, Noel Lynch (London Green Party Coordinator and former London Assembly member), councillors from Scarborough, Lewisham, York, Norwich and Hackney, and members of the Green Party Executive (GPEx), including Campaigns Coordinator, Tim Summers, and Pete McAskie (Management Coordinator).[9] Some members, like Matt Sellwood, while in favour of a Leader system in principle, were opposed to the current referendum because the term of reelection would be extended to two years.

Supporters of Green Empowerment wanted to "uphold the Green Party's long-standing commitment to non-hierarchical structures and 'grassroots' democracy" through "collective leadership". They believed that a single leader "would not only draw attention away from other speakers and the wider Party, but would bring with it risks that the other parties in this country are all too well aware of". The campaign focused on retaining gender balance in party structures, and avoiding the dilution of their radical policies. They focused on success under the Principal Speaker system, seen in the steady buildup of support from the low point of the 1992 general election to the situation at the time of the referendum, where the party has over 100 councilors along with two members of the European Parliament and two members of the London Assembly.[9]

Derek Wall countered pro-leader arguments by stating that "if you are a clear speaker, there's no problem getting coverage and explaining the party's views." He was concerned by the history of past political parties that started off as being participatory until they adopted a single leader system in which the members became "puppets".[8] Wall also opposed the reduction in numbers of Principal Speakers from six to two in 1992, as advocated by the Green 2000 group.[2]

In September 2008 Caroline Lucas was elected as the party's first leader. Lucas was reelected in 2010 but chose not to stand in 2012, when Natalie Bennett was elected her successor. After Bennett stood down in 2016 Lucas returned as leader, this time sharing the position with Jonathan Bartley.[10]

In 2018, Siân Berry replaced Lucas as co-leader, with Bartley continuing in the role.

In July 2021 Jonathan Bartley announced he would be standing down as the party's co-leader at the end of the month, triggering the 2021 Green Party of England and Wales leadership election.[11] Siân Berry remained as acting leader, but decided not to stand in the leadership election due to her concerns over the party's message on trans rights. In her statement, Berry cited unspecified spokesperson appointments as being inconsistent with her pledge to support trans equality.[12]

Prior to 1992 six principal speakers were elected annually.

• Sara Parkin
• Jim Berreen
• Andrew Simms
• Jean Lambert
• David Spaven
• Derek Wall

The Female Principal Speaker post was won by Siân Berry, without a contest.[14]
