Keir Starmer said the UK will not retaliate against US tariffs, warning that a trade war would harm businesses and families. “A tariff war is in no one’s interest.” Starmer said, adding that his priority is to prevent escalation. He stressed that disputes among allies should not be resolved through tariffs and said decisions on Greenland belong to its people and Denmark. Starmer added that continued cooperation with the United States within NATO remains vital for the UK’s security and economy.
