Inventor James Dyson has reiterated he wants Britain to leave the European Union, as he pledged to spend £1 billion on research and development.
The entrepreneur's Wiltshire-based firm Dyson is committing the money on 100 new products over the next four years.
It is also spending a further £200m towards additional production lines in south-east Asia so that it can increase its manufacturing capacity to 11 million motors a year.
The spending is on top of a previously-announced plan for a £250m campus expansion at its Malmesbury site, creating 3,000 jobs.
But Dyson, who is chairman of the company he founded in 1993, again expressed concerns about how the EU operates - adding Britain did not need to be "dominated and bullied".
He also said people coming to the UK to study engineering and science, plus those wanting to develop new technology, should be encouraged to remain.
His comments emerged after details of Dyson's future investment were announced.
The first new research building is due to open in early 2016 and will house laboratories for research and development into future technologies.
Dyson is currently recruiting 300 people to join its team of more than 2,000 engineers and scientists, while it is also planning to extend its external research programme with universities by another £50m.
Dyson works with over 30 universities to develop early-stage technologies, including a £5m investment in a joint robotics lab with Imperial College London, and in fluid mechanics at the University of Cambridge.
Dyson, which last year produced its millionth machine, moved its manufacturing to Asia a decade ago.
The company is best known for inventing bagless cleaners and bladeless fans, with 90% of its technology now sold overseas in more than 70 countries.
