The death of caudillo Francisco Franco, and partly because of the difficulty of explaining outside the Basque Country that reference to ETA, LCR-ETA (VI) changed again its name to LCR.
One of the militants LKI in those years was Germán Rodriguez, which was murdered by the Spanish police in Pamplona on July 8, in the incidents of the Sanfermines of 1978 [es].
[2][3] The following years the LCR supported several local electoral platforms, although in the mid and late 1980s the party generally campaigned in favor of abstention.
In the Basque Country, Liga Komunista Iraultzailea, Langile Abertzale Iraultzaileen Alderdia and Nueva Izquierda formed the coalition Auzolan, which also received support from the EMK.
