The party currently has four representatives in the House of Commons and two in the House of Lords, in addition to more than 890 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, LGBTQ rights and drug policy reform. The party also supports a universal basic income, a living wage and democratic participation. It has taken a pro-immigration stance. 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.
