Cristina Fernandez was being sworn in as Argentina’s first elected female president today, completing a rare husband-wife transfer of power that the nation hopes will ensure continued recovery from an economic meltdown.

A judge issued the second arrest warrant in less than a week against former Argentinian president Isabel Peron, summoning her for questioning about a death squad that terrorised the country during her 1974-76 rule.

Spanish police today said they are awaiting an Interpol order to carry out an arrest warrant from an Argentine judge for former President Isabel Peron, who is believed to be living in Madrid.

A former police officer alleged to have been a member of a far-right death squad active in Argentina during the mid-1970s has been arrested in Spain on a warrant to face murder charges in his native country.
