If Ms May did want to engage the great unwashed on the topic of Defence, and potentially free up a bit of cash, she could start with the QE Carriers. Impressive they might be, but it's a classic case of "hollowing out" with a couple of high end assets and almost nothing in the rear. Let's be honest we've done without them for the last few years and not really missed them, unlike MPA which is a critical national asset that is most definitely required.
Like most other in anyway controversial topics though I feel sure her advisers have made sure she stays well away and carry's on talking about "stability" and "strong Britain", blah, blah, etc, etc
