Lima, February 3 (RHC-teleSUR) -- A legislative commission confirmed Tuesday that two former Guatemalan presidents along with the current president will be called to testify over their potential involvement in a decade-long bribery scheme.

Former presidents Alan Garcia, along with Alejandro Toledo, and current President Ollanta Humala – who could choose not to testify as he is still covered by presidential immunity – will all be heard by the court, the commission's president Juan Pari announced.

A police investigation carried out in Brazil recently found that Brazilian companies have been paying bribes for decades to Peruvian state officials since Garcia's last presidential term until now, in a case known as "Lava Jato."

Garcia and Toledo are both running for the presidential election scheduled for April 10, along with 17 other candidates.

The bribery scheme involves another proponent of neoliberal policies and presidential candidate, Pedro Pablo Kuczynski, Pari said, saying Kuczynski was potentially implicated in the bribery scheme when he was serving as a state official in Toledo's administration. Former and current mayors of Lima - Luis Castañeda and Susan Villaran - have also been called by the court.

Garcia, Toledo and Kuczynski all attended the 6th International Anti-Corruption Conference, organized by the Peruvian treasury inspector's office, that started on Tuesday in Lima.
