BBC: Lancashire election candidates asked to oppose fracking
Anti-fracking campaigners have asked Lancashire council election candidates to oppose the process.
In March, energy company Cuadrilla said it had delayed plans to use the shale gas extraction method in the county until 2014.
Groups including Ribble Estuary Against Fracking and Friends of the Earth made the call at a protest in Preston.
Friends of the Earth's Helen Rimmer said she hoped the candidates would "back renewable energy instead".
