US attorney general finds 'no voter fraud that could overturn election'

US Attorney General William Barr, a top ally of President Trump, has said the Justice Department has found no evidence of fraud in the 2020 election.

"To date, we have not seen fraud on a scale that could have affected a different outcome in the election," said the top US law enforcement agent.

His comments come as Mr Trump has failed to accept defeat.

He and his campaign have filed lawsuits in states that he lost, as they begin certifying Joe Biden as the winner.

Since 3 November's vote, Mr Trump has repeatedly made unsubstantiated claims of widespread voter fraud, and members of his legal defence team have spoken of an alleged international plot to hand Mr Biden the win.
