Before the debate begins, I have to remind Members that, as �Erskine May� says:
�Good temper and moderation are the characteristics of parliamentary language. Parliamentary language is never more desirable than when a Member is canvassing the opinions and conduct of his opponents in debate.�
The reason why that matters in this particular debate and does not really occur in other debates is that this debate is on a substantive motion directly relating to the conduct of the right hon. Member for Uxbridge and South Ruislip (Boris Johnson).
In this debate, because it is on a substantive motion of this kind, arguments intended to criticise or defend that conduct are in order. Therefore things may be said that the Chair would not normally permit in other proceedings. However, those speaking in favour of the motion should set out their arguments clearly. Intemperate abuse is as out of order on this motion as much as on any other.
I am quite sure the right hon. Member for Ross, Skye and Lochaber (Ian Blackford) will already have borne in mind all that I have just said.
