The revelation that ministers are considering bringing Thames Water into temporary public ownership has reopened the fierce debate over the privatisation of the country's water industry. It comes after the sudden resignation of Thames Water’s chief executive and Sky’s exclusive report into government contingency plans for the firm’s potential collapse. On Sky News Daily, host Niall Paterson speaks to business correspondent Paul Kelso about how Britain’s biggest water company came to be on the brink of collapse and the chairman and founder of River Action, Charles Watson, about whether decades of problems with sewage, leaks and supply could lead to the renationalisation of water firms.
