The better Dyson's business does in Asia - the more likely more tax will be paid in the UK by Sir James and his shareholders on the dividends they receive from the profits the company makes in this fast growing region
Post-Brexit no matter what happens, focusing on a growing part of the world makes financial sense and should ultimately be a win for the UK
Dyson saw profits jump by a third in 2018, posting just over a billion pounds last year. By some estimates as much as 70% was powered by Asian growth
Analysts say that with Dyson's increased investment in Asia, there will be a corresponding requirement for more jobs here - as the firm will need British expertise in research and development
Dyson hasn't actually manufactured anything in the UK since 2003, however he is still investing millions/billions on research and development facilities here.
