Mikel Lejarza Eguía (born 1947 in Areatza, Spain)[1] is a former member of the Spanish intelligence service.
During the 1970s, he infiltrated the Basque separatist organisation ETA, providing safe houses in Spain to lodge their commandos.
[1][2] His long-term infiltration concluded with a major police operation in 1975 which resulted in over 150 arrests.
Two of them, after a summary trial, were among the last political prisoners condemned to death and executed under Franco's regime.
[4] His appearance has been surgically altered and, by the time when the film was released, he was still a target for ETA assassins.
