—there is a plethora of other models. In the Westminster system, we tend to see parliamentary committees. In the U.K. that's the case, in Australia that's the case, although in Australia they also have an inspector general, but that inspector general has a remit that allows him to look at all the agencies involved in security and intelligence matters; it's not just one, as we have here. In the U.S., as you know, they have the select committees for Congress and the Senate, which are oversight, in my view.
But parliamentary committees tend to be the more normal model that is used, or a combination of elected officials and judges, which is what we see in Norway. In the Netherlands they are non-elected, so it's quite a mixed bag.
