Whatever his views on Brexit (and I am Remainer), I think credit should be given to Dyson and his team - they are going to be manufactured in the UK and he is paying with his own money for 4000 of these ventilators to be donated to other countries:
He moved his head office to Singapore around the time he was pushing the UK to leave the EU. Manufacturing had already been moved offshore years before that - Malaysia as I recall, though probably elsewhere too.
