How does household debt affect the economy?

More people are falling into debt because they cannot afford basic household bills, according to a charity.

The Money Advice Trust said it helped 150,000 people with household bill debts last year - up 140% since 2007.

Ross Walker, Senior UK Economist at the Royal Bank of Scotland told BBC Radio 5 live's Wake Up to Money that banks taking a "more cautious" approach to lending was one effect.
