Donald Trump has become embroiled in a dispute with Time magazine after claiming he had turned down the chance to be its "person of the year" in 2017.

The US president, who won the award in 2016 after his shock election win, said he was approached by the magazine again for this year. But having been told he would only "probably" be selected, he declined the nomination.

But within hours the magazine hit back, insisting that that Mr Trump was incorrect.

The dispute between the president and the magazine was conducted on Twitter on Friday night.
