Ansaruddin Abdul Malik Alonto Adiong[2] is a Filipino politician serving as mayor of Ditsaan-Ramain, Lanao del Sur since 2022. Previously, he was the representative of Lanao del Sur's 1st district (2013–2022). He was elected vice governor of the Autonomous Region in Muslim Mindanao (ARMM) in 2005. After Governor Zaldy Ampatuan's removal from office in 2009, Adiong became the acting governor until 2011.
A member of a political family of Lanao del Sur, Ansaruddin is the son of the late Mamintal Adiong Sr. and his wife, Bedjoria Soraya Alonto. Ansaruddin and his father both served as provincial governor.[3] His elder brother, Mamintal Jr. is now the provincial governor.
His younger brother, Zia, was the deputy speaker at the last legislative assembly of the now-defunct Autonomous Region in Muslim Mindanao (ARMM) and member of the first interim Parliament of the Bangsamoro.[4] Succeeding Ansaruddin, Zia is currently the district representative.
Adiong was an ARMM assemblyman since 2001.
Adiong and his running mate Zaldy Ampatuan, both ran under Lakas–CMD, were elected vice-governor and governor, respectively, of ARMM in 2005[5] [6] and in 2008.[7] [8]
On December 10, 2009, pursuant to the rule on succession stated in Republic Act (RA) No. 9054, Adiong, also the regional local government secretary, was sworn in by interior secretary Ronaldo Puno to assume the regional governorship vacated by Ampatuan who was taken into military custody for his alleged involvement in the Maguindanao massacre.[9] [10] [11]
He assumed the said post until his successor was appointed in December 2011 by virtue of RA No. 10153.[12] [13]
Adiong initially filed his candidacy for ARMM vice governor for the 2011 regional elections, originally scheduled on August 8 but later synchronized with the 2013 national elections through RA No. 10153.[14] [15] However, he later opted to run for representative of the first legislative district of Lanao del Sur under the Liberal Party (LP).[16]
Adiong was then elected for three consecutive terms: in 2013 (ran under LP),[17] [18] in 2016 (ran under the same party),[19] [20] and in 2019 (under Nacionalista Party or NP).[21] [22]
On May 11, 2017, Adiong, along with five other LP congressmen, transferred to PDP–Laban.[23] In the 2019 elections, he ran under NP.[24]
Adiong was elected chairman of the House Committee on Muslim Affairs of the 18th Congress.[25]
In 2022, Adiong ran under the NP and was elected mayor in his hometown in Ditsaan-Ramain, Lanao del Sur.[26] [27]
