Boris Johnson has greenlit funding for a new multibillion-pound nuclear power station, triggering concerns among some of Liz Truss's allies that it could limit her economic vision.
Whitehall sources confirmed the Prime Minister and Chancellor Nadhim Zahawi have given the go-ahead for financing for the construction of the Sizewell C nuclear reactor in Suffolk.
Private funding will be sought for the project estimated to cost £20-30 billion.
