Left-wing independentist alliance EH Bildu gained 27 seats in the Basque parliament, a six-seat increase from the last election.

Despite EH Bildu's historic success, the conservative Basque Nationalist Party (PNV) is expected to continue governing through a coalition with the Socialists.

The election indicates a shift in Basque Country politics, focusing more on societal issues and less on the historic ties of EH Bildu to the former terrorist group ETA.

The incoming Basque parliament will have a strong nationalist presence, with independentist parties holding at least 54 seats.

Arnaldo Otegi, with past connections to ETA, enters the political scene with EH Bildu, possibly affecting the region's political dynamics.

The success of EH Bildu suggests that the push for separatism extends beyond Catalonia in Spain.

The Basque Country, historically known for ETA's violent independence struggle, is now one of Spain's most affluent autonomous regions.

Outgoing regional leader Iñigo Urkullu is poised to be succeeded by fellow party member Imanol Pradales.
