UKIP are being a little misleading here. Where the ship disembarks any rescued migrants, and should we take 25,000 migrant refugees are two entirely different questions.
HMS Bulwark is unlikely to pluck 25,000 from the sea. But the few they do find they want to take to a nearby port. At present there is no agreement where they can unload there cargo, so unfortunately our kind offer to help has been rebuffed.
We should be deterring Africans from this perilous journey. Granting sanctuary to 25,000 will just encourage more and result in more lives lost, not saved.
Denying HMS Bulwark a port in Italy is more of a UK/Italy dispute than an EU one. The distribution of refugees around the EU is something we can opt out of, and have (for the moment).
So the story is poorly represented by UKIP for cynical electoral gain (or not as the election pans out).
