Local Audit and Accountability Bill [HL]

My Lords, before the noble Baroness sits down, will she kindly explain a point on which I am very unclear? Some time before 2017, someone will have to decide whether the existing contracts are to be extended or not. My view is that they should be extended because they are cost-effective. Who will handle that, and who will deal with the situation that would arise if perhaps a small number of local authorities covered by a particular contract do not wish to renew while the remainder do?
