Negotiations over a technology deal between the UK and US have stalled due to stumbling blocks in wider trade negotiations between the two sides.
The Technology Prosperity Deal - which was billed as "historic" when it was unveiled during US President Donald Trump's state visit in September - saw both countries pledge to co-operate in areas such as AI.
However, talks on the agreement are now being held up because of US concerns about what it considers to be wider UK trade barriers.
A government spokesperson said "our special relationship with the US remains strong and the UK is firmly committed to ensuring the Tech Prosperity Deal delivers opportunity for hardworking people in both countries".
