Europe Ecology – The Greens
It was founded in 1956 by Justin Catayée, beforehand the founder of the Guianese federation of the French Section of the Workers' International (SFIO). It is a separate party, not to be confused with the departmental federation of the French Socialist Party. For instance, the PSG endorsed the overseas list of Europe Ecology – The Greens, not the PS one, in the 2004 European elections.
