Democratic presidential nominee Joe Biden has defeated President Trump, denying him a second term after a bitter campaign and dramatic, prolonged vote count in battleground states that sparked a flurry of lawsuits. 

In a statement he says he is "honoured and humbled" and that it was time for America to "unite".

The Trump campaign says "the simple fact is this election is far from over" and has launched legal challenges 

Trump had earlier declared himself the winner, before all the results were declared.
