Defunct green political party in the United Kingdom
The Green Party, also known as the Green Party UK, was a Green political party in the United Kingdom. Prior to 1985 it was called the Ecology Party, and before that PEOPLE. In 1990, it separated into three regional political parties within the United Kingdom: the Green Party of England and Wales. the Scottish Greens. the Green Party Northern Ireland. Despite the UK Green Party no longer existing as a unified entity, "Green Party" (singular) is still used colloquially to refer collectively to the three separate parties; for example, in the reporting of opinion polls and election results.
