Hungary began dismantling former leader Viktor Orban’s self-styled illiberal rule by imposing term limits for premiers and winding up public trusts that wielded billions of dollars in assets in an extension of his political influence, Bloomberg reports.

Parliament approved the constitutional amendment on Monday, which will cap prime ministerial terms at two four-year stints and disqualify Orban from returning to power. He had served five overall terms, including four consecutive ones from 2010.

This change was one of the main election campaign promises of the current Hungarian prime minister, Peter Magyar. He had earlier stated that he intended to stop the deepening authoritarianism in Hungary and return the country to the EU.
