Ivanka Trump’s Awkward Tweet Mistake Congratulating New UK PM Boris Johnson

Boris Johnson is about to become the Prime Minister of the United Kingdom -- but Ivanka Trump didn't quite get it right.

The daughter of U.S. President Donald Trump, Ivanka Trump, tweeted her congratulations to the incoming Prime Minister, but got one minor detail wrong.

Ivanka Trump mistakenly called the United Kingdom the United 'Kingston'. As far as we know, Johnson is not the prime minister of a delicious biscuit.

"Congratulations @BorisJohnson on becoming the next Prime Minister of the United Kingston," the tweet read.

The gaff comes weeks after Donald Trump tweeted after meeting Prince Charles, only to call the future King the 'Prince of Whales'.

Donald Trump has heralded the selection of Boris Johnson as the new leader of Britain's governing Conservative Party and the United Kingdom's next prime minister, in a possible sign of warmer relations between the two allies.

"Congratulations to Boris Johnson on becoming the new Prime Minister of the United Kingdom. He will be great!" Trump said in a post on Twitter shortly after Johnson's election on Tuesday.

Trump has had tense relations with outgoing British Prime Minister Theresa May despite being hosted for a state visit. Ties were further strained this month following leaked messages by the British ambassador to Washington that referred to Trump; the official later quit.

The U.S. president has repeatedly praised Johnson, the flamboyant former London mayor and pro-Brexit champion who has been compared to the Republican US president, a former reality television host and real estate developer known for his unconventional, combative approach to politics.

Johnson was the overwhelming favourite to win Tuesday's Conservative Party election despite a chaotic private life and a reputation for lies, exaggeration, a lack of seriousness and discipline.

He replaces May, who stepped down after failing to deliver on her Brexit plan to leave the European Union.

Australian prime minister Scott Morrison and former politician Tony Abbott also offered their congratulation to the incoming leader of the U.K.
