The talk that I hear seems pretty clear that if/when Linton closes, the assets will go to Valley. Make of that what you will.
As for the carriers and the F-35, it's like I said before... if you can have Michael Portillo (a hugely experienced former Conservative Defence Minister) and Dianne Abbot (left-winger MP with a finger firmly on the "Real labour" pulse) both sat side by side, saying that the carriers are patently unaffordable and will have to go... I think you can make your own conclusions.
