The PEOPLE Party was founded in February 1972 by Tony and Lesley Whittaker, Freda Sanders, and Michael Benfield, a group of surveyors who were concerned about the state of economics, employment, defence, energy (fuel) supplies, land tenure, pollution and social security, as then seen within an ecological perspective. After the 1975 Conference, PEOPLE changed its name to the Ecology Party to gain more recognition as a party of environmental concern.
The Ecology Party was seen as the second step for Green politics in the United Kingdom. In 1976, the party won its first seats on Rother District Council, East Sussex, and on Kempsey Parish Council, Hereford & Worcester. Jonathan Tyler was elected Chairman of the Ecology Party that same year, and both Tony and Lesley Whittaker took a step back from active involvement in the party. The 1977 Party Conference saw Jonathan Porritt elected to its National Executive Committee. In the 1979 and 1983 General Elections, membership and recognition of the Ecology Party greatly increased. By July 1980, consensus in the Ecology Party was focusing towards decentralisation and non-violent direct action. Following the success of the Social Democratic Party in the UK and Die Grunen in Germany, the Ecology Party resolved to change its name to the Green Party.
The Green Party of the United Kingdom was founded in June 1985. The party had increased success in the 1987 general election. In 1990, the Scottish and Northern Irish branches of the Green Party voted to break away and form their own parties, citing differences in opinion on party policy and the growing support for Scottish independence. The remainder of the Green Party became the Green Party of England and Wales, of which the Welsh and London branches operate with a degree of autonomy.
In 2006, the Green Party of Northern Ireland resolved to amalgamate with, and become a branch of, the Green Party of Ireland.
In July 2018, the Wales Green Party held a vote to decide on whether or not to separate from the Green Party of England and Wales and become a separate party. Of those who voted, 65% voted in favour of the status quo.[1]
All three Green parties used to be members of the Greens-European Free Alliance from its inception until the United Kingdom's departure from the European Union in 2020. The Greens/EFA is the political grouping in the European Parliament, comprising Green and regionalist parties from across the member states.
