She collaborated in the establishment of the Peruvian Nationalist Party, which she currently leads. She was considered a potential candidate in the
2016 Peruvian presidential election, but chose not to run. As of 2017, the Peruvian justice system is investigating her for serious cases of corruption, usurpation of power and money laundering. The funds were allegedly used to finance President Ollanta Humala's election campaign. Along with her husband, she was arrested on 13 July 2017 in connection with this scandal, and was ordered to be held for 18 months. On 15 April 2025, Heredia and Humala were convicted and sentenced to 15 years' imprisonment for money laundering over their involvement in the
Odebrecht scandal. On the same day, she requested
right of asylum for her and her then-underage son, Samin Mallko Ollanta Humala Heredia, at the
Brazilian Embassy in Lima. Following the 1954
Convention on Diplomatic Asylum, to which both countries are signatories, the request was authorized and they fled to
Brazil, landing in country's capital
Brasília on 16 April. ==References==
