The House authorities have made possible virtual participation in the Bill Committee’s proceedings, and it is up to individual witnesses whether they wish to take that up or not. That was always available under the ordinary systems used for some time by Select Committees. It applied to Public Bill Committees as well.
As I was saying, I do expect some teething problems with the voting system today, and it will be some time before our proceedings are fully restored, but in the meantime we must act to minimise the disruption.
