Generally, Ministers are encouraged to attend. But I don't know, in terms of their diaries and what they do, how the communication is between them and the committee. Certainly, it would be much appreciated if they were generally there in the meetings so that they could participate and be able to engage the kind of queries that come when that happens. It should either be them or their deputies. I think that is in order insofar as I am concerned. Of course, people who are always there are directors-general, who are basically the accounting officers. I think we should encourage that, if possible, they should be there at all times. I don't think there is any problem with that.
