Two armed cargo ships left Japan last week on a six-week journey to Britain.

One, the Pacific Pintail, was carrying 250kg of plutonium - fuel for nuclear power stations that Greenpeace claims could make 50 nuclear weapons.

The group is waging an international campaign against the shipment and promises opposition along the route.

The shipment is insured by British Nuclear Insurance (BNI), a pool which includes Royal & SunAlliance and Cox.

Cox chief executive Michael Dawson confirmed the shipment was covered by BNI.
