Biography

Vizcarra was involved in the election campaigns of his brother Martín, assisting him in the 2006 Peruvian general election and the 2011 Peruvian general election. In August 2025, Vizcarra was placed in preventative detention due to corruption allegations involved reported embezzlement.
After being listed as a frontrunner as a presidential candidate in the 2026 Peruvian general election, Vizcarra denied his intention to run, believing his brother would have his disqualification from holding public office overturned and he would be able to run for president. In the poll, about 71% of respondents made the mistake of believing Mario was Martín. Despite this, a later poll showed Vizcarra becoming the second most popular presidential candidate by mid-October 2025.
