"The checking-in is a mechanism for the Lords to get paid. Most of our work is not actually in the chamber of the House of Commons - it's the post we get, the e-mails we get, all the letters we get.

"We don't do that in the chamber. But going in the chamber is a mechanism to pay us so that is why we have to go in to the chamber."
