Families living in 'fuel poverty'

Thousands of people die each year because of fuel poverty, according to an independent report into the problem.
Professor John Hills has called for a new definition of the problem, which focuses on people with low incomes driven into poverty by higher than average fuel bills.
His interim report was published during a period of increased concern about rising fuel costs. The government has called on energy suppliers to hold back on further price increases.
Living in "fuel poverty" is defined by the government as spending 10% of median household income on electricity and gas.
Single mother Charlene Franklin from Birmingham tells BBC's Simon Gompertz how rising fuels costs mean she is sometimes forced to go without food.
