President Donald Trump is "determined to continue with a "10% baseline tariff" against all countries despite his U.K. trade deal, the White House said.

Donald Trump will stand firm on the blanket 10% tariff on most UK imports into the US, his press secretary has indicated, as the Prime Minister declined to rule out the possibility of changes to tech taxes in a future trade deal.

The president held a press conference at the Oval Office on Thursday to announce the agreement, which will see the U.K. reduce tariffs on American-made goods to 1.8 percent.
