President Trump confirmed early Thursday that the US has reached a major trade deal with Britain, saying the agreement marked a “very big and exciting day” for the key allies.

“The agreement with the United Kingdom is a full and comprehensive one that will cement the relationship between the United States and the United Kingdom for many years to come,” Trump said in a Truth Social post.

“Because of our long time history and allegiance together, it is a great honor to have the United Kingdom as our FIRST announcement. Many other deals, which are in serious stages of negotiation, to follow!”

“The Golden Age of America is coming!” he added.

The commander-in-chief signaled that details of the deal would be unveiled in full later Thursday morning during an Oval Office press conference.

“This should be a very big and exciting day for the United States of America and the United Kingdom,” he said.

The deal is the first agreement the Trump administration has struck with a foreign nation since the president announced his plans to impose sweeping tariffs on US trading partners last month. 

It comes after Trump on Wednesday had teased a “major trade deal,” but did not specify which country was involved — only saying it was “big and highly respected.”  

His so-called “Liberation Day” tariffs — unveiled on April 2 — called for the application of a baseline 10% levy against most countries on April 5, followed by steeper reciprocal tariffs that were planned to take effect on April 9. 

The president issued a 90-day pause on the higher rates days after his announcement, claiming that dozens of nations had pleaded for a reprieve in order to revamp trade agreements with the US. 

Britain is subject to the 10% baseline tariff, but was not hit with a higher reciprocal rate.

The US ally is also subject to a 25% import fee that Trump slapped on foreign steel, aluminum and automobiles. 

Treasury Secretary Scott Bessent revealed last month that the Trump administration had “lined up” talks with 70 foreign governments seeking to avoid the tariffs. 

In addition to Britain, Japan, Australia, India, South Korea, Israel and Vietnam were expected to be the focus of Bessent’s initial trade deal negotiations. 

The Trump administration also appears to be nearing deals with India and Israel, according to the New York Times. 

Earlier this week, Trump downplayed the necessity for the US to rush into new trade agreements. 

“Everyone says, ‘When, when, when are you going to sign deals?’” Trump said during an Oval Office meeting with Canadian Prime Minister Mark Carney. 

“We don’t have to sign deals. We could sign 25 deals right now, Howard, if we wanted to,” the president continued, referring to Commerce Secretary Howard Lutnick. “We don’t have to sign deals. They have to sign deals with us.”

Bessent, during an interview with Fox News “Ingraham Angle” host Laura Ingraham, described the president’s seemingly ambivalent attitude toward negotiating new trade deals as the “strategic uncertainty” that is necessary to ensure the US gets “the best deal possible.”

The Treasury secretary is slated to take part in high-level meetings with China over the weekend in Switzerland, which will mark the first trade talks between Washington and Beijing since Trump was re-elected. 

Trump hit China with 145% tariffs over its trade advantage with the US, its role in the American fentanyl crisis, and retaliatory levies the Communist nation has imposed on US exports.
