It became known as the ‘Big Lie’: the notion, formulated inside Donald Trump’s head that he had in fact won the election.
He clung to it even though his own attorney general, daughter, son-in-law and chief of staff as well as all the evidence spelled out he was wrong.
And yet such was the power of Trump that his lie helped to mobilise a mob that came close to overturning American democracy.
