BARE-BOTTOMED protesters let it all hang out yesterday, when they obstructed a government bolthole in Whitehall to call for clean and renewable fuel.

The Reclaim the Power activists congregated outside the Department of Energy and Climate Change (Decc) to rally against the promotion of dirty, coal-powered energy by the Conservative government.

“Wind, not gas” was spelled out on placards and painted on the bums of three campaigners. One other wore a large wind turbine costume for full visual effect.

New Energy Secretary Amber Rudd supports shale gas, according to campaigners, and the Tories have licensed two-thirds of the country for fracking.

Roads in the City of London were shut by police for at least four hours after Reclaim the Power jammed the revolving door of City firm Invesco.

The investment management company — which owns 26 per cent of the Drax coal-fired power station in North Yorkshire — is the former workplace of new Energy Minister Andrea Leadsom.

She worked there for 10 years before she moved to Prime Minister David Cameron’s Cabinet — a testament to the “revolving door” between rapacious corporations and the government.

Activist Matilda Wnek said: “These companies and government are in each other’s pockets and shutting the revolving door will help change the decisions made to ones that are in the public interest, not in the interests of the fossil-fuel industry.”

As part of a nationwide day of action, other campaigners sullied the steps of the Institute of Directors near Piccadilly Circus by tipping bags of coal over them while holding up signs saying: “You can’t clean coal!”

A World Coal Association meeting was to have taken place, but activists shut the delegates out by attaching themselves to the doors using superglue and locks. They eventually found their way in through the side kitchen doors.

Elsewhere, campaigners dressed as shivering grannies with zimmer frames descended on the British Gas headquarters in Staines, Surrey, to hand over a “bill” for funeral costs for the 15,000 that have died because their homes were freezing cold.

Around 6.6 million Britons in total are living in fuel poverty.The group also has protesters camping out in a field near to Didcot B power station — just 20 miles away from Mr Cameron’s constituency in Witney, Oxfordshire — to rally against the expansion of gas power and the harm it is doing to the planet.
