[holding answer 9 September 2009]: The criteria against which we will be short-listing the 20 test hubs were published on 28 September and we have invited local authorities in England, Wales and N Ireland to participate.
The criteria can be found at

We expect to announce the location of these short-listed test hubs by the end of this year or early next year.
