Moïse Katumbi, the first democratically ­elected governor of Congo's mineral-rich Katanga province, has begun to turn the place round since he took over in 2007. The mining sector has been reformed, investment is up and the capital, Lubumbashi, is getting a spring clean. He's done it by personally funding what the province needs (he's from a wealthy mining family) and by taking a hands-on approach to its problems. Katumbi may not be perfect. Before he became governor he was accused of corruption, which he denies. But if more leaders used some of his techniques, life could look up in a lot of African cities.
