While Greens in the UK have always suffered from a grossly unfair electoral system, in the European Union they have been able to flourish as part of a small but effective group of European Greens.
Since their first election in 1999, the UK's Green MEPs have been hugely influential in the European Parliament. Everyone living in modern Britain - and the rest of the EU27 - will have been touched by the causes they have campaigned for, and the progressive policies that have resulted.
If and when Brexit happens, the UK will no longer be represented by MEPs. However, you will still be able to access the websites of the three most recent UK Greens: Jean Lambert, Keith Taylor and Molly Scott Cato.
You can browse their individual websites here, or use the facility below to search for specific terms across all of the sites.
