Thousands joined protests in the Philippines on Sunday, including the Roman Catholic clergy, calling for the resignation of the country’s president and the prosecution of high-level officials over a corruption scandal tied to flood-control infrastructure.

Opposition groups and the Catholic Church marched along Manila’s EDSA Avenue, calling for investigations into President Bongbong Marcos and his administration. Organized by the People’s Movement Against Corruption (KBKK), the demonstration called for accountability in the “Trillion-Peso” scandal, demanded sweeping political reforms, and condemned what protesters described as a pattern of impunity regarding corruption on major public infrastructure projects.

Cardinal Pablo Virgilio David of Manila said protests calling for transparency, accountability and reform must continue across the country. He called the protests a “peaceful revolution” that is in progress. David said that the country’s legislators must pass reform measures to break up political dynasties, which he called one of the “most malignant forms of cancer” in the country. David added: “Democracy cannot function fully until these tumors, especially political dynasties, are removed.”

The “Trillion-Peso” scandal gained prominence in the summer of 2025 after the spread of allegations that billions of pesos intended for flood-control projects were diverted to high-level politicians and contractors. According to the accusations, many projects were overpriced and poorly built using funds from the national budget. Several high-ranking officials have resigned and been arrested, but President Marcos has denied any wrongdoing and involvement in “ghost projects.”

In September, tens of thousands of protesters staged a rally against corruption at Rizal Park in Manila, with segments of the demonstration turning into violent clashes with the police and hundreds of people being arrested.
