Peru's constitutional court has overturned a 15-year jail sentence handed to the country's former president after he was found guilty of corruption. The former president had said he would appeal against the verdict, and now Peru's constitutional court has declared the entire criminal proceedings against him null and void. Humala was released from Barbadillo Prison in the capital Lima on Friday night, with a crowd of supporters on hand to see his release. He said: "The Criminal Chamber currently handling the case must order the definitive dismissal of the proceedings and the FREEDOM of former President Ollanta Humala". When Humala was convicted, his wife Nadine Heredia was also found guilty of money laundering and sentenced to 15 years in prison.
