On the point of order, Mr Chairman: I reject the assertion made by Senator Macdonald. Numerous conversations take place in this chamber. One of them on that side of the chamber, which I heard, included a slur about our leader. If you want to start going tit for tat, we can do that.

The CHAIRMAN: Senator Macdonald and Senator Hanson-Young, I did not hear any of the comments you have referred to. You have both made your remarks, so it is now on record. I propose to take no further action.
