Do you mean about the difference between what's being proposed?
The first half, the first paragraph, is identical to the existing standing order, except for the wording “in 2011”. It has been substituted for “in any calendar year”, and the motion adds a second paragraph. I believe there are three supply periods; it delineates the minimum number of sitting days and the maximum number of sitting days for each of those supply periods. That doesn't presently exist in the standing order.
