Labour leader Jeremy Corbyn has joined anti-fracking protesters on the Fylde to call for an immediate ban on the practice.
He said fracking was "dangerous" to the environment as he met protesters at the site in Preston New Road,
The government said shale gas extracted from fracking has the potential to be "a new domestic energy source".
Mr Corbyn spoke to about 100 anti-fracking protesters outside the Preston New Road fracking site, which has been the focus of long-running protests by environmental groups.
Cuadrilla, which runs the fracking site said it had invited Mr Corbyn to chat to the workforce and have a tour of the site, but he left without taking them up on their offer.
