The identity of Britain’s best-known business figure is always a taxing question. Difficult, because the field is narrow.

I mean someone who is instantly recognisable, who can walk into any bar or restaurant, and people will nudge each other. There are the Dragons’ Den panellists, Lord Sugar, Sir Richard Branson and that’s about it. Unless they’re regularly on TV or if they’ve been involved in scandal, such as Sir Philip Green, they won’t be familiar enough. Not even Sir James Dyson will provoke a response, not everywhere. As for Sir Tim Berners-Lee, who created the world wide web, he enjoys anonymity, except among members of the tech community where he is lauded.
