This is what he said about the hearing,
"Secondly, I hear what the hon. Gentleman says about his Committee conducting an inquiry into the role of the Speaker, and that is absolutely proper—
I think he said something from a sedentary position about tomorrow, with evidence being taken and witnesses being heard, and that is absolutely right. I do not know what he expects me to deduce from that. I would not dream of seeking to comment adversely—still less to trespass, which it would be quite improper to seek to do—upon the legitimate autonomy of any Select Committee of this House. It is perfectly proper for his Committee to undertake such an inquiry. I am entirely untroubled by it, and it is a reflection of his conscientiousness that he should do it."
Basically, he was saying, "Am I bovvered?"
