Peru has lost about 3 billion soles ($860 million) from its public coffers to corruption since 2010, the nation's controller general said Tuesday.

Fuad Khoury presented the dimensions of corruption in Peru at the inauguration of the 6th International Anticorruption Conference, organized in Lima by his office.

The three-day conference will include presentations by the candidates running in Peru's April 10 presidential election.

Khoury said that the Controller General's Office has detected more than 21,500 criminal irregularities committed by more than 11,000 officials over the past six years.

The office launched administrative procedures to punish 7,000 officials since 2011 but up to now it has managed to sanction only 747 of them with punishments of up to five-year bans on holding public office.

Khoury also noted that currently there are 11 regional governors who have had charges filed against them for alleged corrupt acts.

"The pending task is to see how we can solve the problem of decentralization, given that it has transferred a significant percentage of responsibilities without having organized (them properly)," he said.

The first presidential candidate to speak at the conference will be Keiko Fujimori, the daughter of disgraced former President Alberto Fujimori, who has been imprisoned since 2009 on charges of crimes against humanity and corruption during his 1990-2000 tenure. EFE
