RESOLUTE anti-nuclear campaigners entered their fourth day of protest yesterday at Britain’s controversial nuclear weapons factory AWE Burghfield.

Construction workers and their vehicles have been barred from accessing Burghfield after dozens of campaigners decided to respond to allegedly secret works to upgrade the current Trident nuclear deterrent programme.

According to a Nuclear Information Service report, the Atomic Weapons Establishment (AWE) is helping develop a new weapon called “Mark 4A” at both Burghfield and Aldermaston sites.
