Four nuclear protestors blocked the entrance to the Sizewell power plant in Suffolk this morning in a demonstration against proposals to develop the site.

Three women and one man “locked” themselves across the main road into the station, with their arms linked through concrete-encased tubes to prevent workers from gaining access to Sizewell's A and B plants.

Representatives from the Campaign for Nuclear Disarmament (CND) and the Shutdown Sizewell Campaign said the demonstration was triggered by British Energy's announcement earlier this week that the site near Leiston was one of four earmarked for the building of new power stations.

A small group of supporters watched as the campaigners unveiled a banner saying: “Nuclear power is not the answer to climate chaos”.

The demonstrators unchained themselves by 9.30am and were escorted off the site by police.

Peter Lanyon, of the Shutdown Sizewell Campaign, said: “We don't need nuclear power. What we need is energy conservation and more sustainable lifestyles.

“If the government persists in building new power stations we are heading for climate chaos of the most appalling type.”

A spokesman for Suffolk police said: “The protest was very peaceful and no arrests were made. The officers on site took details, but no criminal offences were reported.”
