It's a fair point. We do require witnesses to answer questions.
Actually, looking at the section “Swearing-in of Witnesses”, it says, “refusal to answer questions or failure to reply truthfully may give rise to a charge of contempt of the House”.
We will get to the next intervention, which is Mrs. Atwin's, and then we will have a chance with Mr. Deltell, but we will have a break after the next round. Perhaps Mr. Firth can confer with his lawyer and we can get back to this issue.
Mrs. Atwin, go ahead, please.
