The UK government still supports the Sizewell C nuclear power station and is involved in “constructive” negotiations as it seeks to finalise a deal to fully fund the project “as soon as possible”, press reports have said.

Last week the BBC quoted an unnamed government official as saying that Downing Street wants to “review every major project, including Sizewell C” as it seeks to repair government finances.

However, the prime-minister’s office was quick to deny the claims. “We hope to get a deal over the line as soon as possible,” Max Blain, prime-minister Rishi Sunak’s spokesman, told journalists.

Blain said the reports about Sizewell C being reviewed were “not accurate” and “our position remains the same”, adding negotiations are “ongoing and constructive”.
