In relation to our chamber, there are no criteria. It's a matter for an individual member as to whether to participate in a physical or virtual form. The expectation is that they're treated equitably regardless of whether they're in the chamber physically or coming in electronically.
In relation to committees, it's a matter for the individual committee to determine collectively how it wishes to conduct its business. For example, if the committee is taking evidence from witnesses who might be in different parts of the country, they may choose to do so virtually. If they're doing a legislative scrutiny, they may choose to come together physically, as it's easier to do so in the room together.
In the main, when committees undertake scrutiny of ministers and accounting officers, they want to do that physically. They impose the criterion of what is best for getting our business done.
In committees, I think individuals will have different views, but as a collective, the chairs are very much of the view that it's for them to determine and not for the Senedd or anybody else to impose upon them, within the broad framework of guidance issued by our presiding officer, which applies both to committees and to the chamber.
I hope that answers your question.
