MADRID, Feb 23 (Reuters) – Spain will declassify documents that could shed more light on a 1981 attempted coup that threatened to ​topple its fledgling democracy, Prime Minister ‌Pedro Sanchez said on Monday.

Declassifying the documents was a way of settling a historic debt with the Spanish public, Sanchez said in a post on social messaging ‌platform ​X.

“Democracies must know their past ⁠in order to ⁠build a freer future,” he wrote.

The files, due to be published on Wednesday following repeated requests for their release, may offer fresh insight ​into the role of former King Juan Carlos I, as well as the involvement ⁠of intelligence agencies and ⁠other state institutions.

However, many documents related ​to the plot have disappeared, former spy chief Alberto ​Saiz warned in a 2022 interview with ‌broadcaster La Sexta.

In the failed coup d’etat, Antonio Tejero – a lieutenant colonel in the militarised Civil Guard police force – and a band of ⁠men stormed the lower house of parliament in Madrid.

They fired shots in the air and held terrified ⁠lawmakers hostage for ‌some 17 hours, interrupting the ⁠swearing-in of a new government with ​the ‌aim of forcing a return to ​dictatorship in ⁠the name of the king.

The plot collapsed after Juan Carlos delivered a live televised address backing the democratically elected government and the constitutional order.
