Preliminary results in Haiti's presidential election suggest musician and singer Michel Martelly won the runoff vote on 20 March. He defeated ex-senator and former first lady Mirlande Manigat, officials quoted by news agencies say. Turnout in the second round was high and voting was largely peaceful, although still marred by fraud. Haiti is struggling to rebuild after the January 2010 earthquake and to cope with a cholera epidemic. Final results are not expected until 16 April at the earliest.
