Sir Keir Starmer insisted he would “always put our national interest first” in response to Donald Trump's steel tariffs. The prime minister told MPs the UK would not “abandon” steelworkers amid warnings that the UK steel industry faces a devasting blow when Mr Trump's 25 per cent tax on imports to the US comes into effect next month.

Sir Keir Starmer said the UK was still considering the implications of Donald Trump’s decision to impose tariffs on US steel imports.

President Trump on Monday said he would be imposing 25% tariffs on all steel and aluminum imports into the United States. "This is a big deal, the beginning of making America rich again," Mr. Trump said as he signed the tariff orders in the Oval Office.

Trump said on Sunday he would introduce new 25% tariffs on all steel and aluminium imports into the U.S., on top of existing metals duties, in another major escalation of his trade policy overhaul. Starmer's spokesman said while it was not possible to speculate on the impact of such tariffs without seeing details,

Donald Trump's surprise announcement of plans to impose whopping 25% tariffs on all international steel and aluminium imports to the US could be "hugely damaging'' for the UK. Industry figures reacted with consternation today (Monday) after President Trump spoke of his plans on Sunday as he flew on Air Force One to watch the Super Bowl in New Orleans.
