"I once wrote a book about this which got mischaracterised – British workers produce less per hour than … and that’s a combination of kind of skill and application. [...] If you look at productivity, it’s very, very different in London from the rest of the country. But basically … this has been a historical fact for decades. Essentially it’s partly a mindset and attitude thing, I think. It’s working culture, basically. If you go to China it’s quite different, I can assure you [...] There’s a fundamental issue of British working culture. Essentially, if we’re going to be a richer country and a more prosperous country, that needs to change. But I don’t think people are that keen to change that. There’s a slight thing in Britain about wanting the easy answers. That’s my reflection on the election and what’s gone before it, and the referendum – we say it’s all Europe that’s causing these huge problems … it’s all these migrants causing these problems. But actually what needs to happen is more … more graft. It’s not a popular message."
