Proceedings during the Pandemic

The Leader of the House said earlier that witnesses giving evidence to the Domestic Abuse Bill Committee could attend from afar. I have contacted the witness I invited, who told me that he could not attend from afar because he could not contribute through video, which he takes as discriminating against people who have to travel to London because he cannot stay in a hotel here. I would like the Leader of the House to be clear on what the situation is.
