Children and Young Persons Bill [HL]

Perhaps the Minister would be kind enough to help me with a couple of questions. First, with regard to calculating how many independent reviewing officers are needed, is it possible to calculate how much time IROs give to individual looked-after children and from that how many we need nationally? We want to be assured that there are enough to go around. Secondly, what will the relationships be between the IROs and the social work practices? Will they be monitoring them under some sort of contract monitor, as it were, or will they be monitoring the performance of the local authority and therefore be one step removed from the social work practices?
