The energy secretary said he had changed his mind on nuclear power, because "renewables and energy efficiency can't do it alone" and that nuclear "can be cost competitive".
Ed Davey claimed climate change was "a huge threat to our planet", and said "we have to do everything possible,"
He also spoke to Andrew Neil about Vince Cable's speech on the economy, and a potential tax rise for those earning at least £50,000 a year.
