SEOUL: A high-profile South Korean politician and presidential hopeful resigned on Tuesday as the head of his new opposition party that has been rocked by a bribery scandal. Ahn Cheol-Soo, a former IT software tycoon, stepped down as co-leader of the People’s Party, amid allegations that its members received tens of thousand of dollars in kickbacks from two local companies before legislative elections in April. “All political responsibility for this case rests with me. I put down the co-chairmanship to take all the responsiblity,” Ahn told journalists. Ahn, who is very popular with younger voters, rose to political prominence as a centrist independent candidate in the 2012 presidential election.
