Argentina's vice president Amado Boudou has been charged with bribery and conducting business incompatible with public office.
The allegations relate to the acquisition of the company that prints the country's currency and of later benefiting from government contracts.
Boudou is accused of using shell companies and secret middlemen to gain control of the company that was given contracts to print the Argentine peso and campaign material for the ticket he shared with President Cristina Fernandez.
Federal judge Ariel Lijo's decision was published on the justice department's website.
Boudou is the first sitting Argentine vice president since the nation emerged from military dictatorship in 1983 to face such charges.
He could be sentenced to between one and six years in prison, and banned from holding public office.
Boudou says he is innocent of the accusations.
