Juan José Rosón (25 September 1932 – 19 August 1986) was a Spanish politician and a member of the Union of the Democratic Centre (UCD).

[2] His brother, Antonio (died 1986), served as the president of the Parliament of Galicia and another, General Luis Rosón, survived an assassination attempt perpetrated by ETA in November 1984.

[6] His major initiative was to improve the role of the intelligence services and of the police and security forces in fighting against terrorist attacks under the unified command for the counter-terrorist effort.

[7] To this end he established a coordination unit for antiterrorist logistics, operations and intelligence, Mando Único para la Lucha Contraterrorista (Spanish: Single Command for the Counterterrorist Fight), in March 1981.

At that meeting, which lasted several hours, Manglano unveiled a coup d'état conspiracy that several military officials were preparing that was going to be especially bloody, and that was going to be executed on 27 October 1982, the day before the general election.
