No. It's not up to the minister to interpret the act. The act is quite clear that everything given to me is confidential. If the person who gives it to me releases it, I will comment on it, etc.
Until such time as he releases it, I cannot comment on it. I have the copy of the letter. As he quite rightly said, he copied me in the letter to the Prime Minister. It's in my possession. He has publicly commented on it. He has not released it. The function of releasing is up to him, not to me.
