President Donald Trump has once more turned what ought to have been a simple PR opportunity into an absolute disaster when speaking to a seven year-old who called the US Santa-tracking centre on Christmas Eve.

The toe-curling bungle came as the President and first lady Melania Trump spoke on separate phones to children whose calls to NORAD had been patched through to the White House lines.

Sitting, technically just about together in the same room, but with what body language experts are describing as a ‘void of aching misery, unspoken repressed hatred and deep-deep sadness’ between them, the camera zoomed in as Mr Trump took a call from a seven year-old from South Carolina.

‘What age are you?… Seven… “Are you still a believer in Santa? Because at seven, it’s marginal, right?’ said the President seemingly completely unaware that he was ripping the magic of Christmas to shreds for the little girl by raising the possibility that Santa might not exist.

Mercifully the call ended soon after but not before the President added: ‘OK honey, you just have a great Christmas but be sure to be nice to your Mom and Dad. Because if you aren’t a good little girl then Santa, if he does exist, and by the way, you now know the jury’s out on that one, yeah?’

‘Well he won’t bring you that beautiful dolly you asked for. No way, kid. You’ll join all the other losers and get a piece of horse shit and a lump of coal – coal, that thanks to me by the way – has been mined by our great miners, just the GREATEST miners. FACT! Right, so long as I’m busy now.’
