Thirty protesters currently blocking all entrances to AWE Burghfield
The protest started at 7 am, with people locking themselves to the cars and to each other and the base is now at a standstill.
The use of cars, along with the blocking of all three entrances at once, marks an escalation of protests at the base, which are becoming more frequent as the UK approaches a general election that could determine the future of the Trident nuclear weapons system.
Ministers have already pledged £2billion of taxpayers’ money to the construction work even though Parliament will not make a decision on Trident renewal until 2016.
The people blocking the site are members of the Action AWE group and are calling on all parliamentary candidates to commit themselves to voting against Trident renewal.
Two people have arrested on suspicion of blocking a public highway.
Two cars and a trailer are involved in the protest, with one vehicle at each of three ways in to the site. Of the people involved, around a third are form Wales, with others from Reading, Bradford, Cornwall, London, Norwich and elsewhere. Many are locked to each other, with others standing nearby to provide support and to liaise with police.
There have been several protests at Burghfield over the last two years, but they have generally blocked only one entrance.
The latest protest was on 19 May.
Burghfield is seven miles from the AWE’s other site at Aldermaston.
