The UK is set to be among the countries worst hit if US President Donald Trump's 15% global tariff goes ahead, analysis has suggested.

The UK had negotiated a 10% tariff deal with the US and would be one of the hardest hit, while countries such as China and Brazil which have higher rates would be better off, according to think tank Global Trade Alert (GTA).

The British Chamber of Commerce told the BBC the UK would "sit towards the bottom of league table" of trade partners if Trump's announcement came into effect on Tuesday.

However, US trade representative Jamieson Greer has said trade deals allies had negotiated would still stand. The BBC has asked the UK's trade department for comment.

On Friday, the US Supreme Court outlawed most of the global tariffs that Trump had announced last year, saying the president had overstepped his powers.
