The hon. Lady has mentioned the F-35. The work on that aircraft is based in Alyn and Deeside, which I obviously welcome; it is vital that we have it. However, over the years, there has been a lot of uncertainty regarding that site because of the chopping and changing that has happened, with the MOD changing how contracts are placed and moving work forward or back. We need longer-term planning if we are to maintain that important strategic work.
