Sizewell is already approved - so what's different this time?published at 08:23 British Summer Time 10 June
After again being pressed on the government's U-turn on winter fuel payments, Miliband is asked by Justin Webb on the Today programme what is different from previous announcements on Sizewell C.
(As a reminder, regulators approved Sizewell C during the previous government.)
Miliband says the difference is "that we're funding it - we're putting forward the money to make it happen".
He says this is the biggest investment in nuclear in half a century.
"We are doing this because we want long-term energy security," he adds.
