Authorities in China ordered Didi to stop taking new ride sharing customers, and banned the sale of the app, because of data sharing issues. Investors in the newly floated company are furious, but this isn’t the first kind of regulatory intervention China has made. So what’s behind this crackdown? As numerous sporting events take place this weekend we’ll be looking at the political power wielded by sports stars and what that means for the brands that sponsor them. We’ll head to a geo-thermal plant in Cornwall, UK, to find out whether the industry could provide secure, reliable renewable energy in a de-carbonised world.
