As China suffers its worst blackouts in over a decade, on Business Weekly we ask what’s causing the power shortages and what they mean for the rest of the world. We also hear from Germany, where political wrangling over who will be the next Chancellor continues. The Green Party will play kingmaker - and there are hopes from people in flood-hit areas that environmental policies will take centre stage. Plus, have you ever wondered how valuable influencers can be for a brand? We spend the day in a luxurious mansion full of social media personalities to find out if they represent value for money. And as James Bond takes to the silver screen once more, we ask whether the studios can afford to retire 007. Business Weekly is presented by Lucy Burton and produced by Matthew Davies.
