The 120 figure is our starting point for what we thought we could most easily manage over the course of a two- to two-and-a-half-hour session. To be honest, I wouldn't say it's an arbitrary figure, but we had to start from somewhere. In the average two or three hours of a House of Commons session, you wouldn't normally get to 120 members. You might do, but it's mainly a technical limitation. Likewise, the limitation of numbers of members physically in the chamber, which is around 50, is based on the physical distancing measures we've put in place with signage, blocking off some seating, and so on.
They're both driven, in effect, by logistics.
