Get it right
The MP's log in and sit in front of their cameras. The Speaker sits in front of his monitor to see who's there, and use the chat box to say you wish to comment. Then selects those to comment...
Now that's the up side sorted, the down side is using the BBC Parliament Channel, that's how they are seen. Best brush hair (as appropriate) and not be wearing their giraffe onesy. They can scroll the names of those MPs who are actually logged on, and use facial recognition software to make sure that they've just left their Spitting Image puppet in front of the webcam.
Boris is still on his sick note, so shouldn't be working anyway.
That's how it should work, however I doubt if the honourable members would put up with it for long.
