The Political aspects of De la Rua´s resignation: In late 2000, a political scandal broke out when it was reported that the SIDE, Argentina's intelligence service had paid massive bribes to a number of senators to approve a controversial Labor Reform Act. The head of SIDE, Fernando de Santibañes, was a personal friend of De la Rúa. The crisis came to a head on October 2000, when Vice President Carlos Álvarez resigned, citing De la Rúa's unwillingness to tackle corruption.
During March 2001 another crisis finally caused the resignation of all the FrePaSo Cabinet ministers, leaving President de la Rúa without political support. The congressional elections of October 2001 were a disaster for the government, which lost many of its seats in the Senate and the House of Deputies to the Peronists. The election results marked also a growing unrest within Argentina's voters, who took to cast millions of null or blank votes. After losing during mid-term elections for congress in October 2001, de la Rúa pledged to continue his economic policies of austerity, but appeared weaker. When riots broke out in December, and he failed to obtain the necessary support from the opposition Peronists, he had no choice but to resign. By December 20 and after a series of riots, De La Rua finally resigned. Ten days later pay-back installments of the huge Argentine foreign debt payment (over US$ 140 billion) were defaulted (suspended).
