Two battleground states, Wisconsin and Arizona, certified their presidential election results in favour of Joe Biden, even as President Donald Trump’s legal team continued to dispute the results.

Mr Biden’s victory in Wisconsin was certified following a partial recount that only added to his 20,600-vote margin over Mr Trump, who has promised to file a lawsuit seeking to undo the results.
