Donald Trump has refused to say whether he will accept the outcome of the presidential election during the third and final TV debate with rival Hillary Clinton.

After weeks of election-rigging claims, Trump once again blamed a biased media and election fraud for an unfair election and said he would wait to see what happened.

The debate began as an issue based clash over topics such as abortion, immigration and gun control, but later became full of personal attacks.

Clinton who leads in national polls, this was her chance to show why she is best suited to succeed President Obama.

For Trump the debate was his last chance to try and swing the elusive undecided voter.
