Alright here are my results (Putting myself down as a dirty, dirty Pom):

LibDems are my closest party in terms of the EU integration, but in terms of domestic policy it is The Greens. Overally it is 59.8% Greens and 56.7% LibDems.

My nearest party in Europe are the Iniciativa per Catalunya Verds (Initiative for Catalonia Greens), followed by teh Portuguese Humanist Party and then other various Socialist and Communist parties.
