The chairman of energy firm EDF's has said is "confident" that the Hinkley Point C nuclear power station will go ahead.
In a letter to staff, Jean-Bernard Levy, said although the financial context was "challenging", the project had the support of both the French and British governments.
I am sure that this project is a good project for the group and that in the near future, all the conditions will come together for it to be definitely launched.
He added that negotiations with the French government to secure the company's financial position were continuing and insisted EDF would not be involved until his conditions were met.
Plans for the power station in Somerset have been beset by delays and uncertainty over funding.
EDF's chief financial officer Thomas Piquemal also resignedover concerns the decision on investment at Hinkley Point C was being made too quickly, potentially threatening the firm's financial position.
On Monday, the government said it "continues to fully support the Hinkley Point C nuclear project".
Thomas Piquemal has resigned ahead of a final decision on the company's planned financial investment in the £18bn nuclear power plant.Read the full story ›
Energy supplier EDF has recorded a £903 million UK profits haul in the first half of the year, as Britons were charged more to turn up the heating.
