President Donald Trump has filed his latest legal challenge in his attempt to overturn the projected election victory of Joe Biden.

His lawyers filed a lawsuit in Michigan to try to block certification of the result there. The state has been called for Joe Biden, with a current projected lead of 2.6% - close to 150,000 votes.

Jake Rollow, of the Michigan Department of State, said the lawsuit "does not change the truth: Michigan's elections were conducted fairly, securely, transparently and the results are an accurate reflection of the will of the people".

With Alaska becoming a projected Trump victory on Wednesday, only North Carolina, Georgia and Arizona are yet to be placed in either camp.

Mr Trump only leads in North Carolina and he needs all three, plus the overturning of at least one other state projected as a Biden win to have any chance.
