Trump said the baseline tariff level could be much higher for other countries than the 10% that Britain agreed to.

The government has hailed the new deal with the US as positive for the UK, but many have pointed out that tariffs are still higher than they were a few months ago. On Thursday, both Keir Starmer and Donald Trump were keen to play up the agreement that saw tariffs lowered on both sides.

The planned deal was the first outlined since Trump began his stutter-step efforts to rewire the global economy by dramatically increasing import taxes in an attempt to increase domestic manufacturing.
