Energy company Cuadrilla has confirmed that it has started exploratory oil drilling in West Sussex as anti-fracking protests at the site entered a ninth day.
A Cuadrilla spokesman said: "We started test drilling at 11.15am, and we will do a 3,000ft vertical well. We will be there for two to three months."
The project has been subject to days of delays because of high-profile protests designed to halt delivery of trucks and equipment to the plant.
