The former leader of the Green Party has claimed fracking is a "climate crime" as the process to extract shale gas begins in Lancashire.
Natalie Bennett appeard on the breakfast show to discuss fracking which is now underway in the northern county, despite fierce opposition from local residents and environmental campaigners - including fashion designer Vivienne Westwood.
"What was committed yesterday at Preston New Road was a climate crime," Ms Bennett told Julia Hartley-Brewer.
"What we've got here is a a potential start of a whole new industry locking us in to a gas future."

The process of fracking involves drilling deep into the earth and directing a high-pressure water mixture at the rock to release the gas inside.
Lancashire County Council turned down planning applications to frack on the Fylde coast in 2015, but this was overruled by Sajid Javid the following year.
"It's going to use huge quantitiites of water and we're already talking about potential water restrictions in part of the country. I was listening to the planning officer saying don't worry about the gas flaring you can always get blackout blinds," Ms Bennett said.
"This industrialisation of the countryside in Britain doesn't make any sense at all".
