Peru’s unpopular congress is under pressure to annul a controversial law, dubbed the “pro-organized crime” law, which experts argue weakens the fight against extortion and assassination by no longer classifying them as organized crime, which carries stiffer penalties.

Moreover, the law stipulates that to carry out raids on suspected criminals, police and prosecutors must wait for their legal representatives to be present before conducting an operation. In practice, this can mean hours of waiting, allowing suspects to destroy evidence or otherwise frustrate the process.

"A raid is an investigative mechanism that requires surprise," said Solis, adding that the law was instigated by "people in political positions who are being investigated for corruption".

It is perhaps no coincidence that Boluarte -- whose disapproval rating reached a record low of 92% according to the polls this month -- was herself subject to a raid on her home amid allegations swirling around her collection of Rolex watches and luxury jewellery in April.
