Robert Peston explores China's dramatic economic slowdown and its potential impact on Britain, revealing how China has built up one of the biggest debt bubbles in world history.

With chancellor George Osborne championing ever closer links to China, Robert Peston explores the country's dramatic economic slowdown and its potential impact on Britain.

Visiting a ghost city and deserted factories in the north east, Peston reveals how China has built up one of the biggest debt bubbles in world history, and questions whether China's economic woes are worse than Beijing is admitting.

In the booming south, Peston hits the shops to explore whether China can spend its way out of the slowdown - in the face of debts still growing by hundreds of billions of pounds a year.
