Notice served to campers protesting at Hinkley Point
Energy supplier EDF has served notice to anti-nuclear protesters who have set up camp on the site of the proposed Hinkley Point C nuclear power station.
A group of about seven people have been occupying an old farm building.
They are angry that EDF has been allowed to carry out preparatory work before planning permission was granted.
An EDF spokesperson said works were approved by West Somerset Council in July last year following normal planning procedures.
"We have entered into a Section 106 agreement with the local authorities which sets out a number of conditions allowing us to undertake the work and will be commencing that work later this month," the statement continued.
"This follows three years of extensive formal engagement and formal consultation about the project.
"We would hope that these individuals will choose to leave of their own accord but if not there are options available to us.
Protester Shana Stone said they would continue to "fight them all the way."
"This isn't just about Hinkley Point, it's about defending democracy, the rights of future generations and the entire direction of Britain's energy policy," she added.
EDF Energy was granted permission to carry out site preparation works including fencing, drainage, excavation and earthworks in July last year.
A planning application for a new power station was submitted to the Infrastructure Planning Commission in October.
Further public consultation is taking place and a final decision will be made by the energy secretary.
