I've not yet done a really detailed analysis of who's physical and who's virtual. Ministers so far have tended to appear in person, partly because the Speaker has said it's easier to manage the chamber, from his point of view, if the ministers are there.
We've had a mixture of two ministers answering questions, one virtually and one physically. It helps if the minister has significant technical problems that we have someone in the chamber, but no, some London-based members of Parliament have contributed virtually. Some members have come from a distance to participate physically. The data is all published now so people are already looking at it to see what patterns they can see.
