Perhaps we could persuade Mr Cameron to part with some more of the £13n overseas aid budget and buy them. Flotel, international aid platform, refugee lifeboat - ideal.
And whilst I'm sure we will all bask in the glory of having 2 mahoosive aircraft carriers; they are overkill for our foreseeable level of use for them. The deck size and shape are designed for cat & trap ops - fill it with helicopters if you like but its one hell of a hi-value asset to go skulking around the littoral with. They will take some defending and we don't have that many assets to throw around.
