STORY: Two out of nine magistrates in Colombia's National Electoral Council have requested an investigation be opened into Petro's 2022 campaign over alleged spending and financing violations, two sources said on Wednesday.

Speaking at an event in Cartagena, Petro called the move 'deeply unconstitutional.'

The request for the investigation will next be analysed by all of the electoral council magistrates, who will make a decision on whether to formally open the investigation, sources said.

If the investigations go ahead, Petro's case would go before the impeachment commission of the chamber of representatives.

The sources said preliminary investigations found campaign contributions exceeded legal limits by 6 billion pesos ($1.5 million), as well as payments and contributions from two unions that were not recorded in the campaign's accounts and chartered flights provided by an aviation company.
