Green Party of England and Wales

The Green Party of England and Wales (GPEW; Welsh: Plaid Werdd Cymru a Lloegr), often known simply as the Green Party or the Greens, is a green, left-wing political party in England and Wales. Since October 2021, Carla Denyer and Adrian Ramsay have served as the party's co-leaders. The party currently has four representatives in the House of Commons and two in the House of Lords, in addition to more than 800 councillors at the local government level and three members of the London Assembly.

The party's ideology combines environmentalism with left-wing economic policies, including well-funded and locally controlled public services. It advocates a steady-state economy with the regulation of capitalism, and supports proportional representation. It takes a progressive approach to social policies such as civil liberties, animal rights, LGBT rights, and drug policy reform. The party also supports a universal basic income, a living wage, and democratic participation. It is split into various regional divisions, including the semi-autonomous Wales Green Party, and is internationally affiliated with the Global Greens and the European Green Party.

In 1990, what was then the UK-wide Green Party – which had initially been established as the PEOPLE Party in 1973 – divided into the Green Party of England and Wales, the Scottish Greens and the Green Party Northern Ireland. Since 1990, they have been three completely separate and unique political parties, with their own separate leaders, membership, policies etc. The Green Party of England and Wales went through centralising reforms spearheaded by the Green 2000 group in early 1990, and also sought to emphasise growth in local governance, doing so throughout 1990. In 2010, the party gained its first member of Parliament in its then-leader Caroline Lucas (although Plaid Cymru's Cynog Dafis was elected on a joint ticket in the 1990s). As the party's support is spread out across England and Wales, and has rarely been found in electorally significant clusters, the party held only one seat in the House of Commons from 2010 to 2019, before reaching four seats in 2024. The Green Party supports replacing the UK's first-past-the-post voting system with proportional representation, which would grant all parties a share of seats in Parliament based on their national vote share. The party saw an increase of support in 2025 from voters dissatisfied with Labour.
