It seems to be fairly consistent, Mr. Reid.
In each case the chambers have a regular schedule per week, not unlike in the House. That's not to say that each rubric of that schedule is used every week, but for the most part it is, and there's a fixed schedule of set times for a certain part of business to be taken up. For example, in Westminster Hall, on a certain day a time is reserved for e-petition debates, and there's one hour for the liaison committee. There's even a section, I believe, on Thursday for backbench business.
