AURIGA - Since its rapid expansion in the early years of this century, Indonesia’s coal sector has become a main source of funds for political campaigning, both at the national and regional or local levels. Individuals with business interests in the coal industry are playing important roles in the 2019 presidential election, in the campaigns of both Joko Widodo-Ma’ruf Amin and Prabowo Subianto-Sandiaga Uno. Candidates and their campaign teams are deeply connected with the coal sector.
