Broadly, my problem with the resignation is that she has lost the job but is otherwise unscathed. Had she been sacked it would be far harder to give her another cabinet job when the next leader arrives, or a committee chair now, or, come the next election, just automatically reselect her. Those are all things that affect her. Losing this post is by comparison small beer.

And this is not vindictiveness but an attempt to treat the disregard of Parliamentary seriously.
