IN April 2024, major political parties formed an alliance called the Bangsamoro Grand Coalition (BGC) to advocate for inclusive, peaceful and honest midterm elections in May 2025. The coalition is made up of the Salaam Party, headed by Sulu Gov. Abdusakur Tan; the Bangsamoro People's Party, led by Basilan Rep. Mujiv Hataman, the last governor of the defunct Autonomous Region in Muslim Mindanao (ARMM); the Serbisyong Inklusibo-Alyansang Progresibo, led by Lanao del Sur Vice Gov. Mohammad Adiong; and Al-Ittihad-Ungaya sa Kawagib nu Bangsamoro, led by Maguindanao del Sur Gov. Mariam Mangudadatu.

The BGC, affiliated with both the Moro National Liberation Front (MNLF) and the Moro Islamic Liberation Front (MILF), is also composed of traditional, well-supported politicians with significant followings. During the May 2022 national elections, these politicians endorsed Ferdinand Marcos Jr. and Sara Duterte for president and vice president, respectively.
