The hon. Gentleman has made his own point in his own way, and he has used the device of a point of order to register his discontent. Let me say this to him. The convention—and it is not a rule or a law—is well established, although I am sorry to say that it is frequently honoured as much in the breach as in the observance, a phenomenon that tends to be exacerbated in the run-up to an election.

I would prefer Members to resolve these matters satisfactorily without their having continually to be aired on the Floor of the House. I am sympathetic to the hon. Gentleman, but I think that he must now rely on his own devices to ward off repeat performances that he judges to be discourteous.
