Here is the latter.

“Because of our long time history and loyalty together, it is a great honor to have the United Kingdom as our first announcement,” he wrote. “Many other deals that are in serious stages of negotiations to follow!”

Mr. Trump is expected to announce the Oval Office deal at 10 am

The president had not specified which country is part of the deal in his position late on Wednesday evening. On Thursday, a high British officer confirmed that a deal with the United States had been reached.

The British officer, who spoke on condition of anonymity because of the sensitivity of the issue, did not offer any details, except that the deal would be good for both Great Britain and the United States.

The agreement would be the first deal that was announced since Mr Trump imposed rises on dozens of American trading partners. Later he temporarily paved that to enable other nations to reach agreements with the United States.

Details of the agreement were not immediately clear. Both countries have discussed the lowering of British rates on American cars and agricultural products, as well as the removal of British taxes on American technology companies. It was also not clear whether the agreement was actually completed.

Timothy C. Brightbill, an international trade lawyer at Wiley Rein, said that the announcement would probably be “only an agreement to start the negotiations, whereby a framework of issues must be discussed in the coming months.”

“We suspect that tariff rates, not -Tariff barriers and digital trade are all on the list – and there are difficult problems to tackle all these,” he added.

The Trump government has tried to caunish other countries to reach rapid trade agreements with the United States. The president imposed rates for dozens of trading partners on 2 April, but quickly taken back after Paniek followed the bond market. Mr. Trump paused most of those rates for 90 days so that the United States could negotiate trade agreements with other countries.

But he has left a worldwide rate of 10 percent, including on Great Britain. In contrast to other countries, Great -Britain was not subject to higher ‘reciprocal’ rates, because it buys more from the United States than it sells.

Great -Britain is also subject to a rate of 25 percent that Mr Trump has placed on foreign steel, aluminum and cars, taxes that British officials have pushed their American counterparts to lift.

Mr. Trump’s interest to conclude a trade agreement with Great Britain dates from his first term, when his advisers negotiated with the country, but did not complete an agreement. Since Brexit, British officials have also viewed a trade agreement with the United States as a way to compensate for weaker relations with Europe. In the Biden government, British officials continued to insist on a deal with the United States, but made little progress.

For the British Prime Minister, Keir Starmer, the Handelsdeal would be justified for his diligent cultivation by Mr. Trump. During his visit to the Oval Office in February, Mr. Starter came with an invitation from King Charles III For the president to pay a rare second state visit to Great Britain.

The Trump government seems to approach deals with India and Israel and continues to negotiate with South Korea, Japan, Vietnam and other countries. Yet Mr. Trump again showed his unpredictable approach to economic policy on Tuesday when he The prospect of trade agreements triggeredsay that other countries needed such agreements more than the United States.

“Everyone says:” When, when, when are you going to sign deals? “” Said Mr Trump, at one point that moved to Howard Lutnick, his commercial secretary. “We don’t have to sign deals. We can now sign 25 deals, Howard, if we wanted to. We don’t have to sign deals. They have to sign deals with us.”

Trade experts have said that Mr Trump may intend to announce much more limited deals than traditional trade agreements, which cover the most trade between countries and require the approval of the congress. Historically, free trade agreements have cost the United States for more than a year to negotiate.

In his first term, Mr Trump again negotiated various American trade agreements, including a free trade agreement with South Korea and Nafta. But he also signed a series of more limited “mini-deals” with countries in which they lowered or agreed to talk the rates for a few types of goods to talk about a few sectors.

British officials have also negotiated with the European Union and on Tuesday agreed for a trade agreement with India. The India deal would lower the rates between countries and gain more access for British companies to the insurance and bank sectors of India, including changes. The announcement followed for almost three years of negotiations.
