Trump's massive Prince Charles gaffe

President Trump regularly tweets about the "fake news media", but it seems he's shared a bit of fake news himself with a recent royal blunder.

The US leader spent three days in the UK earlier this month and met several royals while he was there, including the Queen, Prince Charles and Camilla, Duchess of Cornwall.

While the state visit seemed to go down fairly well, Trump has now stuck his foot in his mouth with a hilarious mistake shared in a tweet.

Apparently he was a little confused about what exactly Charles is prince of, tweeting that he met with "the Prince of Whales" while in the UK.

No, not Wales, as in the UK country bordering England, whales, as in the actual animals.

The typo was included in a tweet where Trump aimed to challenge "fake news" about an interview he had recently given, where he told ABC news that he would listen if a foreign government offered him damaging information about political rivals in the 2020 election.

He suggested that he wouldn't necessarily report the offer or the information to the FBI either, all of which is very much illegal under campaign finance law.

"I just met with the Queen of England (U.K.), the Prince of Whales, the P.M. of the United Kingdom, the P.M. of Ireland, the President of France and the President of Poland," he tweeted.

"We talked about 'Everything!' Should I immediately call the FBI about these calls and meetings? How ridiculous! I would never be trusted again."

The petulant tweets and strange quotation marks around 'everything' were also cause for discussion, but "Prince of Whales" took the cake online and has since inspired a smorgasbord of hilarious ocean-themed memes.

Countless photoshopped images of Prince Charles as a whale and with whales flooded twitter, as well as hilarious edits of Trump meeting with actual whales instead of the prince.

An edited Welsh flag also made several appearances, with the dragon at the centre of the flag swapped out for – you guessed it – a whale.

Meanwhile news site WalesOnline got in on the jokes by changing their Twitter name to 'WhalesOnline' and adding a whale emoji for good measure.

Though Trump is likely very put out that people are more interested in the memes than his original tweets, we're sure he'll survive.
