Energy Secretary Ed Davey gives fracking the go-ahead

The government has given the go-ahead for a firm to resume the controversial technique known as fracking to exploit gas in Lancashire.

Fracking involves creating little explosions underground, then injecting water and chemicals to release gas trapped in cavities in shale rocks.

Energy Secretary Ed Davey told the House of Commons that fracking would have to meet strict safety and environmental impact conditions.
