ANKARA A South Korean high court decided Monday to postpone its hearing on presidential frontrunner Lee Jae-myung's subornation of perjury case until after the June 3 presidential election, Yonhap News Agency reported. The ruling followed two similar moves by the judiciary last week. The Seoul High Court said the first hearing in Lee's subornation of perjury trial, slated for May 20, has been changed to a later date as the defendant registered as a presidential candidate last weekend.
