See Cabinet Order 65
With MoFA, Welly has served excellently, and I don’t think there’s anyone else who’s as good at FA.
With MoD, there’s only a handful of people who have the experience and activity to serve, and it’s also helpful to have the previous PM as a cabinet member in regards to the transfer of power and continuation of the last term’s projects.
With MoI, there’s a few projects Trivalve has been working on that are close to completion and I’d like to see them through without any of the hiccups of a different MoI.
