The race to find a new leader of the World Trade Organization has been thrown into renewed uncertainty after the cancellation of a key appointment meeting following the US presidential election.

The Geneva-based WTO, which acts as an international arbiter for trading disputes, said it had put off a meeting scheduled for Monday that had been called to appoint Nigeria's Ngozi Okonjo-Iweala as its next director general.
