President Trump was mocked online today after writing about the 'Prince of Whales' in one of his tweets.

The hot-tempered President was quick to jump on to Twitter to respond to a news report which claimed he said he'd listen if foreign governments offered him 'dirt' on opponents.

But in his apparent fury, he misspelled Wales, the country in the United Kingdom, when referring to the title of Prince Charles.

Trump tweeted: 'I meet and talk to "foreign governments" every day. 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. We talked about "Everything!"

'Should I immediately call the FBI about these calls and meetings? How ridiculous! I would never be trusted again. With that being said, my full answer is rarely played by the Fake News Media. They purposely leave out the part that matters.'

Donald Trump referred to the 'Prince of Whales', rather than the Prince of Wales, in a tweet today. The message was later corrected to 'The Prince of Wales'

The President with the Prince of Wales, Prince Charles, last week. Today, he referred to Charles as 'The Prince of Whales' in one of his angry tweets about 'the Fake News Media'

Trump quickly amended his tweet after he was mocked online for describing Charles as the Prince of 'Whales'

The reference to Whales, rather than Wales, caused hilarity online, with many Twitter users imagine how such a prince might look.

One joker wrote: 'Who is next? The Queen of Bees? The Prime Minister of Elephants? The King of Kong? What a time to be alive...'

Trump later amended his tweet to describe Charles as the prince of the principality of Wales rather than of sea mammals.

Others pointed out that the Queen of England is not the correct title for Queen Elizabeth II, who is actually Queen of the United Kingdom, although Mr Trump did write 'U.K.' in brackets.

Some thought it strange that the underlying suggestion of the tweets was that the the British Royal Family might have information on Joe Biden or other Democrat opponents.

Mr Trump later deleted the tweet and replaced it with one that spelled Wales correctly.

Twitter users were quick to imagine what a real 'Prince of Whales' might look like

The President is believed to have been responding to a report on ABC News which quoted him as saying he would 'want to hear' other countries' information on political opponents.

The channel quoted him as saying: 'If somebody called from a country, Norway, [and said] "we have information on your opponent" -- oh, I think I'd want to hear it.'

He also suggested he might not report any such offer of information to the FBI.

His remarks are of interest in the U.S. due to ongoing claims of Russian involvement in his election campaign.

The title Prince of Wales is traditionally bestowed on the heir to the British throne, Wales being one of the four countries that make up the United Kingdom, along with England, Scotland and Northern Ireland.

Prince Charles met Mr Trump last week for tea in London as part of the U.S. President's state visit to Britain.

In an interview last week, Mr Trump said: 'We were going to have a 15-minute chat and it turned out to be an hour-and-a-half and he did most of the talking - and he is really into climate change and I think that's great.'

'He wants to make sure future generations have climate that is good climate as opposed to a disaster - and I agree,' he said.

But Trump also suggested he doubted the science that shows that the earth is getting hotter due to human activity, an issue on which Charles has been an advocate for a global response.

Today is not the first time Mr Trump has posted unedited tweets. In 2017, he caused a sensation online with the message: 'Despite the constant negative press covfefe'.

When he was President-elect in 2016, he misspelled unprecedented in the tweet: 'China steals United States Navy research drone in international waters -- rips it out of water and takes it to China in unpresidented act.'
