Several banks have started offering the opportunity to bet against Thames Water's debt. It's the latest sign of an impending crisis at the UK's biggest water supplier, after it was labelled 'uninvestable' by its own shareholders. We talk through the company's options and what they could mean for customers and the government, with Bloomberg's Tasos Vossos and restructuring expert Linton Bloomberg from Reed Smith. Hosted By Caroline Hepker and Yuan Potts.
