Piers Morgan has revealed that Donald Trump fell victim to a hoax caller pretending to be the Good Morning Britain presenter.

Speaking on the BBC's Americast podcast Morgan explained that the prankster rang the former US president while he was on Air Force One.

It only became evident that he was talking to a fake Piers Morgan when Trump rang the real Morgan out of the blue while on his way to vote in Florida.

The pair had fallen out over Morgan criticising Trump's handling of the pandemic.

Morgan described the prank call as "a hilarious story," adding "somebody had called him pretending to be me the day before and got through to him on Air Force One and they had a conversation with Trump thinking he was talking to me".

The identity of the alleged prankster remains unknown. If Trump was duped, he would not be the first prominent figure to be fooled.

In March last year, the Duke of Sussex was reportedly tricked into speaking about his decision to quit the royal family by Russian hoaxers posing as activist Greta Thunberg.

Morgan is a long-time acquaintance of Trump and in 2008 won US Celebrity Apprentice, which was hosted by the billionaire businessman.

They had been friendly during Trump's time in the White House before their fallout last year.

Morgan said Trump was a "useless leader" because of his "character flaws - the chronic narcissism, the desire to make everything about himself".
