The conservative Basque Nationalist Party was illegal in 1969 when two of its members died fighting against the Fascist regime of Franco. This is enough for the current Delegate of the Spanish Government in the (Western) Basque Country, Carmen Alba, to ban a planned homage to Jokin Artajo and Alberto Asurmendi, members of this party, who died when the bomb they were preparing exploded, killing both.
No wonder, after all those elements are the direct heirs of Franco and his minions. And they know it.
