Republican presidential frontrunner Donald Trump said he would only accept the result of the U.S. elections if he wins the presidency. 

The announcement came after Trump expressed his doubts on the legitimacy of the U.S. election process ahead of the final presidential debate on Wednesday in Las Vegas, Nevada.

Lagging behind Democratic presidential candidate Hillary Clinton in various polls, Trump claimed that he was being forced to waive his right to contest election results.

“I would like to promise and pledge to all of my voters and supporters and to all of the people of the United States that I will totally accept the results of this great and historic presidential election, if I win,” said Trump at a rally in Delaware, Ohio.
