US President Donald Trump has said he is raising the global tariff he wants to impose to 15%, up from the 10% he had announced a day earlier.

Mr Trump said in a social media post that he was making the decision “Based on a thorough, detailed, and complete review of the ridiculous, poorly written, and extraordinarily anti-American decision on Tariffs issued yesterday,” by the US Supreme Court.

After the court ruled he did not have the emergency power to impose many sweeping tariffs, Mr Trump signed an executive order on Friday night that enabled him to bypass Congress and impose a 10% tax on imports from around the world.

The catch is that those tariffs would be limited to just 150 days, unless they are extended legislatively.
