British Prime Minister Keir Starmer and US President Donald Trump talked about taking forward talks on a UK-US economic prosperity agreement in a telephone call on Sunday evening, a Downing Street spokesman said.

In a statement, Downing Street affirmed that both leaders termed the talks as “productive” and highlighted the requirement for ongoing conversation. The talks are scheduled to continue this week, with Starmer and Trump vowing to keep close touch over the coming days.

The UK is looking to negotiate a deal with the US to avoid more general reciprocal tariffs affecting trade. Trump hinted Friday that he might agree to make individual deals with nations looking to escape upcoming US tariffs. But he emphasized such deals would only be under consideration after his administration puts new reciprocal tariffs into place, to be announced on April 2.

Trump admitted that some nations, including Britain, had already gone to the US in an attempt to negotiate trade agreements that would enable them to avoid the tariffs.

As trade relations between the two countries hit a critical point, both governments are attempting to reach a solution that fosters economic expansion while dealing with possible trade hurdles. Additional negotiations are likely to determine the framework of a potential agreement in the next few weeks.
