GroenLinks (Green-Left) was officially formed in 1990 from a grouping of four smaller left-wing and green parties – the CPN, EVP, PPR and the PSP. The party’s core values are environmental sustainability and social justice, but it has a bit of a leftist intellectual image and has never been in government. Current leader and bright spark Jesse Klaver is just 30 and has been an MP since 2010. website
