In the wake of widespread blackouts across the UK earlier this week, Brown commented that the UK's nuclear programme needs to be "more ambitious", signalling the government may consider additional nuclear power plant sites to those already selected.
Brown said: "We want to do more to diversify our supply of energy and that's why I think we are pretty clear that we will have to do more than simply replace existing nuclear capability in Britain."However, the Prime Minister has been attacked by Liberal Democrat MPs over the proposals, who say the focus should be on alternative means of power generation.
Liberal Democrat Shadow Environment Secretary, Steve Webb said: "Gordon Brown is drawing totally the wrong conclusion from soaring oil prices. New nuclear power plants won't deliver any power for over a decade."
He continued: "Nuclear power is not the answer to today's energy crisis. The Government should be focusing on greater energy efficiency, boosting renewables, and making sure that coal fired power stations do not pollute the environment."
