I am very grateful to the hon. Gentleman. If I understand his point of order correctly, the answer to it is that the customary method of acknowledging the intention of another Member to intervene, and perhaps the acceptance of that intervention, is a gesticulation with the hand, at which, among other things, the hon. Gentleman excels. [Interruption.] No, no, I think Mrs Main is a bit confused; it is not about the fact that someone seeking to intervene gesticulates, but the fact that the Member on his or her feet signals acceptance. That has not happened and therefore the Leader of the Opposition has the Floor. The position is extraordinarily straightforward.
