Donald Trump has shared an eerie video on the eve of the Iowa caucuses in which he appears to proclaim himself God’s chosen emissary on earth, sent to deliver America back to prosperity.

The three-minute clip, posted to Truth Social on Sunday evening, opens on grainy footage of an LP turning on a record player, broadcasting an apparently ancient “sermon” in which the speaker intones: “And on 14 June 1946, God looked down on his planned paradise and said: ‘I need a caretaker.’ So God gave us Trump…”

What follows – set to a picture of the Republican tycoon as a toddler, followed by a montage of scenes from his presidency – is an extraordinary expression of Mr Trump’s Messiah Complex, bordering on sacrilege.
