Activists have gathered from across Europe to support Action AWE

Anti-nuclear protestors gathered from 5am to lie across the two entrances to the site to prevent vehicles from entering.

The activists have travelled from around Europe for the protest, which is one of an escalating number organised by Action AWE.

The group is stepping up protests to increase political pressure in the run-up to the General Election.

In 2016 the Government is expected to decide whether to spend more than £100 billion on a new generation of Trident nuclear weapons for the next 50 years.

Opponents are undertaking a series of peaceful actions next month aimed at raising public and political awareness of the costs and consequences of nuclear weapons.

A spokesperson for AWE said: “AWE recognises the democratic right of individuals to participate in lawful and peaceful protest activities.

“We have been working closely with both Thames Valley Police and the Ministry of Defence Police to ensure the safety and security of the Aldermaston and Burghfield sites and to ensure the impact on local residents is minimised.”
