David Cameron has restated his commitment to the environment despite reports he told aides to "get rid of all this green crap".
The Prime Minister played down suggestions of a U-turn on green policy after newspapers reported a senior Tory source describing his determination to strip out green levies which push up energy bills.
"The Prime Minister is going round Number 10 saying 'We have got to get rid of all this green crap'. He is totally focused on it," the source said. "We used to say 'Vote Blue, Go Green', now it's 'Vote Blue, Get Real'."
Downing Street said it "did not recognise" the phrase but while meeting supporters of the HS2 high-speed rail project outside Number 10 this morning, Cameron was asked by journalists whether he still believed in the environmental agenda.
"This is a part of it," he replied. "We have got the world's first green investment bank, we have got great support for our green technology industries. We have got the first nuclear power station since 1995. This is a government investing in important green technologies."
Ahead of the 2010 general election, Cameron highlighted his commitment to the environment with a trip to the Arctic Circle to view the impact of global warming, and told voters they could "Vote Blue, Go Green". He has regularly stated his determination to lead the "greenest government ever".
But he dismayed some environmentalists by telling the House of Commons last month that he wanted to "roll back" the green levies, which add an average £112 a year to households' energy bills to fund renewable power subsidies and programmes to insulate homes.
Downing Street said this did not mean the PM had abandoned his commitment to the environment.
