Spain is also an enemy of Athens now that the popularity of the People's party (PP) led by Mariano Rajoy has slumped and he faces defeat in an election later this year.
Mr Urkullu is furious that the PP government has failed to ease ETA's journey to disarmament.
A highly vocal "victory or nothing" PP lobby, backed by influential newspapers, is often blamed.
But the PP has recently calmed down.
Podemos may come first in such regions as Asturias and Aragón, with the PP or PSOE winning elsewhere.
Only eleven days later, on December 30th, he brought in thumping tax rises on income, savings and property.It was the sort of ploy Mr Rajoy's Socialist predecessor, José Luis Rodríguez Zapatero (who preferred indirect taxes), never dared to make, not least because Mr Rajoy's right-wing People's Party (PP) would have accused him of bleeding middle-class wage-earners dry.
Some see a leftist group girding itself to battle a right-wing reformist People's Party (PP) government, led by Mariano Rajoy, that is likely to win power in the next election.That analysis may be right, to judge by a recent open-air assembly on the economy, with a few dozen participants squatting on the paving stones of Madrid's Plaza del Carmen.
With Spaniards slowly turning their backs on the Socialists and PP, the big two parties which jointly fell short of winning 50% of votes at the European elections, whoever wins the next elections is likely to form either a coalition or minority government.
Mr Rajoy stood by his man and the PP paid for his defence.
Some see it that way, including Catalonia and Valencia, whose (PP) chief launched the idea; both might get lots more money that way.
The latest polls put the government of José Luis Rodríguez Zapatero eight points ahead of the PP.
