"I promise you this - I will be a President for all Americans - whether you voted for me or not". Joe Biden has given his first reaction to his election victory tonight - declaring it is time to get past the anger and the harsh rhetoric - to unite, and to heal.

A message which Donald Trump does not appear to be taking on board - threatening to launch legal action "beginning Monday". This is how it finally happened - after four long days and nights of limbo. Just over two hours ago the state of Pennsylvania was called for Mr Biden - its 20 electoral college votes giving him the majority he needed.
