Biography

Datuk Seri Aminuddin bin Harun (born 2 January 1967, Kampung Pachitan, Port Dickson) is a Malaysian politician serving as the 11th Menteri Besar of Negeri Sembilan since May 2018 and as Member of Parliament for Port Dickson since November 2022 [1]. He is a member of PKR, a component party of the Pakatan Harapan coalition [1]. Aminuddin received his secondary education at Sekolah Menengah Kebangsaan Tanah Merah, Port Dickson, before studying business at the MARA Institute of Technology, now UiTM [1]. From 1991 he served a five-year tenure as an investigative officer in the Anti-Corruption Agency (now MACC), before joining Golden Hope Furniture Sdn Bhd in 1995 and subsequently MCIS Safety Glass (M) Sdn Bhd as a senior executive from 1996 to 2008 [1]. He was previously a member of UMNO, serving as its Division Secretary of Kampung Pachitan and Division Youth Secretary of Jimah between 1995 and 1998, before joining PKR in 1999 [1]. He was first elected to the Negeri Sembilan State Legislative Assembly for Sikamat in March 2008 and has held the seat since [1]. After Pakatan Harapan won the 2018 Negeri Sembilan state election, Aminuddin was sworn in as Menteri Besar at Istana Besar, Seri Menanti [1]. He won the Port Dickson parliamentary seat in GE15 (November 2022) with a majority of 23,601 votes [2]. He was reappointed as Menteri Besar for a second term after the 2023 state election, when PH and BN secured a supermajority [1]. In 2026, a constitutional dispute over the Negeri Sembilan royal succession triggered a political crisis, and on 5 June 2026 the state assembly was dissolved, with a snap election set for 1 August 2026 [3]. He also serves as PKR Vice President and PKR Division Chief for Port Dickson [1].

Known for

Aminuddin Harun is defined politically by his tenure as the PKR Menteri Besar of Negeri Sembilan, first appointed in 2018 and reappointed after the 2023 state election [1]. He is recognised for his emphasis on attracting investment to the state, citing RM32.22 billion in investments during his first five-year term and championing the Malaysia Vision Valley 2.0 development project [4]. He became the MP for Port Dickson in 2022, succeeding Anwar Ibrahim in that seat, and in 2026 is the central figure in both the state's snap election and a constitutional dispute over the Negeri Sembilan royal succession [5].

Political positions

On economic development, Aminuddin has consistently positioned Negeri Sembilan as an investment destination, highlighting RM3.0 billion in MIDA-recorded investments in Q2 2024 and advocating for the Malaysia Vision Valley 2.0 project and a proposed Southern Gateway Economic Corridor linking Negeri Sembilan, Melaka, and Johor [6]. On housing and welfare, he pushed for four People's Housing Projects (PPR) in Desa Tanjung, Senawang, Ladang Siliau, and Rantau, securing RM150 million in federal funding, in response to rising housing costs in urban areas [3]. On agriculture and poverty eradication, he has advocated using state land for modern, AI-assisted farming and large-scale cattle farming to commercialise youth agricultural ventures and reduce hardcore poverty [4]. On digital infrastructure, he committed to 4G broadband coverage across all populated areas and 5G deployment in key urban centres [7]. In the 2026 royal succession dispute, Aminuddin maintained that the four Undangs' declaration removing Tuanku Muhriz was invalid and continued to govern on the instruction of the Yang di-Pertuan Besar [1]. He accepted the Unity Government leadership council's decision to maintain PH-BN cooperation in May 2026, following UMNO's temporary withdrawal of support [4].
