Will only accept 'clear election result', says Donald Trump

Republican White House hopeful Donald Trump said on Thursday that he would accept a “clear election result” next month, but reserved the right to challenge the outcome if he felt it was “questionable.”

Trump stuck firm to his unprecedented defiance of US democratic norms, telling supporters: “I will totally accept the results of this great and historic presidential election -- if I win.”

But he went on to say: “I will accept a clear election result, but I will also reserve my right to contest and file a legal challenge in the case of a questionable result.”
