US President Donald Trump has said that he will impose global tariffs of 15%, as he continued to rail against a Supreme Court ruling that struck down his previous import taxes.
Trump said on Friday that he would replace the tariffs scrapped by the court with a 10% levy on all goods coming into the US.
But on Saturday, he announced on Truth Social that this would be increased to the maximum allowed under a never-used trade law.
These will come into force on Tuesday 24 February and can only stay in place for around five months before the administration must seek congressional approval.
The new 15% tax rate raises questions for countries such as the UK and Australia which had agreed a 10% tariff with the US.
