Two companies have pulled out of plans to develop a new generation of nuclear power plants in the UK.
RWE Npower and E.On have announced they will not now invest in new plants in Anglesey and Oldbury-on-Severn, near Bristol.
The government says it is disappointed but there remains "considerable interest" in the project.
