US nuclear weapons could be sited at RAF Lakenheath as early as spring, the Campaign for Nuclear Disarmament (CND) has warned.

The CND’s new general secretary Sophie Bolt told dozens of protesters outside the Suffolk airbase on Saturday: “We are very very concerned about the threat of a nuclear escalation between nuclear-armed Nato and nuclear-armed Russia.

“What’s happening here at this base is absolutely central to this growing nuclear threat in eastern Europe.

“It’s also the horrific genocidal war we are seeing in the Middle East because again it’s F35-A jets here and fighter pilots based here that are involved in that war. 

“This base completely ties the UK to the complicity of genocide that is being carried out against Palestinian people.”

Green Party peer Jenny Jones said it is “obviously incredibly dangerous” to site nuclear bombs in Britain due to its size and international importance.

She added: “If Russia decide to get really heavy not just with Ukraine but other countries, then we could be a target even if they just think we have nuclear weapons here. 

“Secondly, it’s really undemocratic. We need a public debate about the common sense or the lack of it in siting nuclear weapons in Britain.

“We should have a debate in Parliament about this and it should be a free vote as well so we can see exactly what all MPs say about this issue.”

Former Australian minister Melissa Parke, executive director of the International Campaign to Abolish Nuclear Weapons, noted last month’s serious fire at BAE Systems nuclear submarine shipyard in Cumbria; Sellafield nuclear processing plant’s fines for cyber security failings; and maintenance issues on Britain’s nuclear fleet.

She said: “So fires, cyber security failings, maintenance problems on nuclear subs, I mean what could possibly go wrong?

“We are standing on the edge of the nuclear abyss. And our governments have the responsibility to keep us safe; and what are they doing? They are pushing us over the edge.”

Nuke Watch’s Peter Burt described detailed analysis of official documents by scientists, plane spotters and campaigners.

He said: “It’s very clear that we need to keep a close eye on what’s happening here.

“What there is no substitute for is eyes on the ground … in the same way we had in the 1980s we had the Cruise Watch Network, who kept tabs on what’s happening at Greenham Common.”
