Labour says it will insulate 2m houses in first year to cut bills

Ed Miliband says move will ease energy price crisis and reduce dependence on Russian gas

• Where Britain's journey to insulation went wrong

Labour has said it would insulate 2m houses within a year to slash bills and reduce reliance on Russian gas, accusing Boris Johnson of a shameful" failure to stop Britain's homes leaking heat.

The government put major nuclear and offshore wind projects at the heart of its energy security strategy announced earlier this month, but faced criticism for failing to include any new measures on insulation despite the UK having some of the draughtiest housing in Europe.
