Activist investor asks Rio Tinto to give up its primary London listing

A UK-based activist investor has called for Rio Tinto to abandon its London listing and unify its corporate structure in Australia instead, the Financial Times reported on Thursday. Palliser Capital, which has taken up a stake in Rio Tinto, said that the metals and mining behemoth's dual corporate structure is a "barrier to its strategic plans, which made it difficult to do major acquisitions," the FT reported.
