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.
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".
