Fracking: Coastal Oil and Gas Ltd backs Osborne support
A businessman who owns the main licence to drill for gas in south Wales, has welcomed Chancellor George Osborne's commitment to exploring new ways of plugging the UK's energy gap.
Gerwyn Williams of Coastal Oil and Gas Ltd says initial test results estimate £120bn worth of gas could be recovered in one area of south Wales alone.
But methods of extracting the gas are hugely controversial.
