In election turmoil in Spain red-green left nearly doubles its vote

In Spanish local and regional elections of May 22, 2011, the Popular Party (PP) trounced the Socialists (PSOE):
37,56 percent of the vote for PP to 27,81 of the vote for the PSOE.
The red-green alliance of Greens, Communists and other leftists took 6,32 percent of the vote, a higher percentage than the alliance received in national elections since 2000.
(You can see additional details in this wikipedia article (English)).

And this was leaving out the traditional bases of strongest voter support in Spain for the left, Andalusia and Catalonia, which will have their elections later due to a different election cycle.
