On a point of order, Mr Speaker. At Defence questions on 8 January, I asked the Defence Procurement Minister a very straightforward question about HMS Argyll—the type of question to which I would expect him to have an answer at his fingertips. Instead he said, as quickly and as curtly as he could, that he would write to me with an answer. It is almost three months later, and I regret to inform you and the House that I have received no such information from the Defence Procurement Minister, and neither have I received an acknowledgment that he intends to write to me.

May I ask your advice, Mr Speaker? When right hon. and hon. Members have a slippery Minister on the hook and that Minister chooses to wriggle off it by promising to write, what recourse do we have when the Minister does not write?
