Beware of getting in the way of liv. She will have the job if she wants it.
Firstly Livvy is female and no doubt a member of Emilys list. She will have a cohort of female executives and politicians behind her who will knife and character assassinate any male who raises doubts about her suitability for any role at all.
Secondly, Livvy is well connected on both sides of politics.
Thirdly, In my opinion, the "scientific management tribe" which believes that anyone can manage anything if they are "scientific" about how they do stuff are in the ascendant. This is the MBA qualification mantra; practical experience is irrelevant to them. If Liv wants the job then of course she can do it! Don't look for any industry objections.
Fourth, I would expect that any internal competitor will find their career in ruins if they challenge her. So don't look for staff or management objections.
