According to The Telegraph, Donald Trump has ordered that the Gulf of Mexico be renamed the Gulf of America, but Britain will not use that name.

Until the new term that Mr. Trump ordered is widely used in English, Britain will continue to refer to the body of water by its current name.

After claiming that the ocean basin was "ours" and that the US performs "most of the work there," the US president gave the US Board on Geographic Names instructions to rename the gulf within hours of taking office on Monday.

The name will change on official maps in the US within 30 days. Some navigation apps, including Google Maps, are under pressure from Republicans to change it immediately.

However, Mr Trump cannot change the name used by other countries or by international organisations because the gulf is an international body of water with coastlines in the US, Mexico and Cuba.

The Telegraph understands the name will not change on official maps in Britain unless “Gulf of America” becomes the most commonly used name for it by English speakers. Officials believe that is not likely for some time, if at all.

A source said the gulf’s name “cannot be universally changed by a single country” and that the new name ordered by Mr Trump “will not apply to UK products”.

The name change is likely to create controversy at the UN, which has an expert advisory panel on contested place names.

The UN refers to the Falkland Islands, the British name for the south Atlantic archipelago, but provides the Argentinian name “Malvinas” in brackets on official documents.

Mexico has already objected to Mr Trump’s decision, arguing that other countries will continue to refer to the 617,800 sq mile ocean basin by its historic name.

“For us, it is still the Gulf of Mexico, and for the entire world it is still the Gulf of Mexico,” said Claudia Sheinbaum, the Mexican president, on Tuesday.

She previously joked that Mexico should refer to the US as “Mexican America”.

Mr Trump first revealed his plans for the gulf in a press conference on Jan 7, when he said the ocean body was “ours”·

He said: “We’re going to be changing the name of the Gulf of Mexico to the Gulf of America, which has a beautiful ring that covers a lot of territory.

“What a beautiful name. And it’s appropriate… and Mexico has to stop allowing millions of people to pour into our country.”

On Monday, he issued an executive order within hours of taking office to change the official name used by the federal government.

The order, titled “Restoring names that honor American greatness”, said that the gulf would “play a pivotal role in shaping America’s future” and would be renamed the Gulf of America “in recognition of this flourishing economic resource and its critical importance to our Nation’s economy and its people”.

In the same order, Mr Trump renamed Denali, North America’s tallest mountain, after William McKinley, the 25th US president.

The mountain was historically known as Denali by the local Koyukon people in Alaska, but was renamed Mount McKinley by a gold prospector in 1896.

The official name was changed back to Denali by the Obama administration in 2015, in recognition of its heritage and importance to native peoples. Mr Trump has now reversed that decision.

The Telegraph understands that the UK will follow Mr Trump in renaming the mountain on official maps, since it is located entirely within the US and therefore within the jurisdiction of the US Department of the Interior.
