Donald Trump refused to concede the US presidential election even after tweeting that Joe Biden had won the race for the White House — his first public acknowledgment of defeat since the vote nearly two weeks ago.

Mr Trump’s comments came in a barrage of tweets on Sunday morning, a day after he cheered on thousands of supporters in the streets of Washington who urged him to keep contesting the result of the vote.

An early post on Sunday morning suggested the president was coming to terms with the outcome. “He won because the Election was Rigged. NO VOTE WATCHERS OR OBSERVERS allowed, vote tabulated by a Radical Left privately owned company, Dominion, with a bad reputation & bum equipment that couldn’t even qualify for Texas (which I won by a lot!), the Fake & Silent Media, & more!,” Mr Trump wrote even though no evidence of systematic fraud has emerged.
