Jamie Borwick is either brave or reckless. He has sunk the entire £14m he made from selling a family stake in Manganese Bronze, the manufacturer of the iconic London black taxi, into a green vehicles company. In Coventry. Where factories typically close rather than open. And all this at 52, when many business figures are winding down, not gearing up.

But Mr Borwick has a vision of his electric trucks and minibuses trundling quietly and cleanly around big cities, delivering goods and people. Not just in the UK, but all over the world.
