Designer Vivienne Westwood joins anti-fracking rally

Anti-fracking campaigners have been gathering at Westminster to voice their opposition to shale gas extraction.

The protest came as an influential committee of MPs called for fracking in the UK to be put on hold.

The Environment Audit Committee warned that the process was not compatible with the UK's work to cut greenhouse gas emissions and could derail efforts to tackle climate change.

The BBC's Sarah Corker visited the protesters and spoke to acclaimed fashion designer Vivienne Westwood, who is a fierce opponent of fracking.

She suggested fracking was not a financially viable solution to energy needs, describing it as "absolute madness".
