The Colombian Congress has launched an investigation into former president Alvaro Uribe's alleged role in an illegal wiretapping scandal.
The probe will look into the former president's alleged involvement in the intelligence service's illegal wiretapping of opposition judges and reporters.
Eight former officials, including Uribe's Chief of Staff Bernardo Moreno, have already been sanctioned over their role in the surveillance, reports indicate.
Uribe said recently he was ready to assume responsibility for Moreno's actions.
Moreno is charged with failing to denounce an illegal wiretapping case of the country's intelligence service.
Meanwhile, Uribe's agriculture minister, Andres Felipe Arias, is also being investigated on charges of funneling millions of dollars of state money earmarked for poor farmers to a handful of wealthy landowners and industrialists who helped finance Uribe's 2006 presidential campaign, AFP reported on Tuesday.
