SEOUL (Reuters) - South Korea's former prime minister and acting president Han Duck-soo ended a short, ill-fated attempt to win the conservative party's presidential nomination on Sunday after days of internecine disputes just days out from the election.

Rival Kim Moon-soo was chosen as nominee for the People Power Party after party members voted on Saturday to retain him over Han, whose late entry into the race derailed the consensus over its candidate for the June 3 presidential vote.
