Professor Marshall has already faced the expected low-level questions. Will she be a busybody? Does she already have enough powers? Will anyone pay her the slightest attention? As far as the last point is concerned, she has shown she is no slouch at commanding the headlines, even if not always in the way she would wish.
The new commissioner's major challenge, which was underlined only too clearly by the conference delegates, will be the prevailing climate that surrounds her responsibilities. She will have to make clear that promoting and safeguarding the rights of children strengthens, rather than weakens, family life. The two are not inimical.
Commissioners in other countries will also be quick to warn Professor Marshall not to become overloaded with issues of child protection and disadvantage. There are wider interests to consider, as the UN's Professor Jacob Doek pointed out. The new commissioner plans to be inclusive: her constituency should be as well.
