It is not really that aspect that is a problem for me. I can well imagine that ministers tend to work after dinner and to spread documents out on their dining room table, for example, or to open up documents in their hotel room, go and do their ablutions, and then come back to them, etc.
I would like to know what you tell them when you give them specific information as to the way of guarding these documents vis-à-vis those people admitted into their private life.
