Rio Tinto Group survived an attempt by an activist investor to force it to review its dual listing structure, with not enough of its shareholders backing the proposal.

An overwhelming majority of Rio Tinto , shareholders sided with the board to vote against an activist fund proposal that the mining company should review its dual listing in Sydney and London.

Rio Tinto shareholders voted against an independent review of the miner’s dual-listed structure, rejecting an activist investor’s proposal aimed at getting the company to drop a decades-old primary London listing.
