Gunnar Birgisson (born 1947), Icelandic politician, a former member of Alþingi and the former mayor of Kópavogur
The initial attempt failed however as a group of Alþingi representatives rejected the new party's platform – which was inspired by that of Tony Blair's New Labour – and broke away before the merger to found the Left-Green Movement (Vinstrihreyfingin – grænt framboð), based on more traditional democratic socialist values as well as green politics and euroscepticism.
In the 2013 Icelandic parliamentary election he was elected to the Alþingi.
