Ronnel Arambulo

Ronnel Gondraneos Arambulo (born May 18, 1976) is a Filipino fisherman, environmentalist, and activist who is currently the vice chaiperson of Pamalakaya. In the 2025 Philippine Senate election, he ran under the Makabayan slate but lost.

Early life and education Arambulo was born on May 18, 1976 in Malakaban, Binangonan, Rizal and graduated from Janosa National High School. He also enrolled in the University of Manila in 1995, before dropping out a year later.

In July 2021, he had been part of a coastal protest in Botolan, Zambales, marking five years since the Permanent Court of Arbitration issued its pro-Philippine ruling on the South China Sea dispute. He would go on to lose the election after placing 39th, gaining 3,846,216 votes.

On December 4, 2024, Arambulo and 74 others filed the second impeachment complaint against Vice President Sara Duterte, citing betrayal of public trust for her office's alleged misuse of confidential funds. By February 2025, it was consolidated with two other complaints into a single impeachment complaint and signed by 240 lawmakers out of 305, reaching the 1/3 vote threshold and impeaching Vice President Duterte.

On January 26, 2026, Arambulo and 35 others filed the second impeachment complaint against President Bongbong Marcos, citing his potential involvement in the "BBM Parametric Formula" used by the Department of Public Works and Highways, which they alleged to have allowed systemic corruption in government, as well as his alleged involvement in kickback schemes and unprogrammed appropriations.
