sentences:  The commission, whose initial aim was to investigate the alleged presence of secret files on citizens constituted in the Swiss Ministry of Defence, was created in March 1990 in the wake of the "Fichenaffäre" or Secret Files Scandal, during which it had been discovered that the federal police, BUPO, had maintained files on 900,000 persons (out of a population of 7 million).Since the existence of P-26 was revealed a month after similar revelations made in Italy by the premier Giulio Andreotti, who disclosed to the Italian Parliament the existence, throughout the Cold War, of a Gladio stay-behind anti-communist paramilitary network headed by NATO and present in most European countries, Switzerland formed a parliamentary commission charged with investigating alleged links between P-26 and similar stay-behind organizations.It was one of the three countries, along with Belgium and Italy, to create a parliamentary commission on these stay-behind armies.
