LONDON, April 3 (Xinhua) -- British Prime Minister Keir Starmer said on Thursday that Britain is "prepared" for the economic impact of U.S. tariffs while continuing to negotiate a deal.

Addressing business leaders at 10 Downing Street, Starmer said, "Last night, the President of the United States acted for his country. That is his mandate. Today, I will act in Britain's interests, with mine."

He said that decisions made by the British government in the coming days and weeks will be guided solely by the national interest.

"Nobody wins in a trade war," Starmer said, adding that his country will "fight for the best deal for Britain ... But nothing is off the table."

He went on to highlight Britain's ability to remain calm in the face of uncertainty: "One of the great strengths of this nation is our ability to keep a cool head.... We have a range of levers at our disposal."

Speaking to local media on Thursday morning, British Business and Trade Secretary Jonathan Reynolds said he is "disappointed" by the additional tariffs imposed on Britain, describing the 10 percent tariff as not a "fair reflection of how we currently trade." Enditem
