Watching Mark Arbib’s resignation press conference yesterday, it seemed pretty clear that he was absolutely genuine about his desire to spend more time with his family and help heal the wounds from Labor’s appallingly messy 18-month assassination job on Kevin Rudd.

Given that his wife, former Michael Costa chief-of-staff Kelli Field, is making plenty as an associate director at Macquarie Bank, Arbib can probably afford to take some time out.
