Prosecutors who uncovered Brazil's biggest corruption case called on Friday for tougher prison sentences and more legal powers to crack down on rampant graft that costs taxpayers more than the annual budget for education and health. Hoping to ride a wave of national disgust over the latest corruption scandal at state-run oil company Petrobras, the top federal prosecutor's office known as PGR sent Congress proposals to stiffen penalties for corruption to up to 25 years in prison, Reuters reported. The prosecutors are seeking legal reforms to speed up the arrest of corruption suspects and seizure of their assets before they can be hidden. They also proposed reducing Brazil's long appeals process that often lets criminals go scot-free. -- SPA 22:19 LOCAL TIME 19:19 GMT تغريد
