Rio Tinto says 19.35% of shareholders voted for dual-listing review

MELBOURNE, May 1 (Reuters) - Rio Tinto RIO.AX, RIO.L said on Thursday that 19.35% of its shareholders had voted for a review of the company's dual-listed structure.

Under UK regulations, a vote of 20% or more would have required the company to consult more widely with shareholders.

Activist investor Palliser Capital has campaigned for Rio Tinto, which is listed in London and in Sydney, to unify the two into a single holding company in Australia.

Palliser argues that doing away with the current structure could unlock $28 billion in value for holders of Rio Tinto's London shares.
