GUATEMALA CITY (Reuters) - Guatemala was bound for a presidential election run-off after the three leading candidates split Sunday´s vote, prolonging political uncertainty just days after a graft scandal toppled the president.

Otto Perez resigned as president on Thursday and spent election day in jail while a judge considered charging him over a customs corruption racket, plunging the poor Central American country into its worst political crisis in two decades.
