Sir James Dyson upbeat about Brexit as company invests in expansion

The billionaire inventor believes Britain can now reach trade agreements with countries outside Europe more easily

Sir James Dyson, the billionaire inventor, has said there is no reason for businesses in Britain to be uncertain as a result of the EU referendum and that they would be mad to withhold investment on the back of the vote.

Speaking as his company, Dyson, unveiled a 250m expansion of its research and development centre in the Cotswolds, the engineer said Britain could now reach trade agreements with countries outside Europe "much more easily and flexibly" and reconsider its approach to immigration from around the world so it can attract more engineers and scientists from India, China and the far east.
