I am not sure that Black Rod keeps his surprises up his sleeve. In answer to the noble Lord, I have no detailed knowledge—they would not be surprises if I knew them.
My Lords, notwithstanding the understandable caveat in the first Answer of my noble friend the Chairman of Committees, has there been any indication from members of staff, including police and custodians, that security issues may arise from the sharp increase in the number of visitors to the House, which is a welcome development but may pose problems like this, partly because many are sent by MPs to visit this House as well?
The noble Lord makes an important and valid point; it is always a matter of proportionality. We want to encourage people to visit their Parliament—that is absolutely right—but at the same time we have a responsibility regarding security, not only for Members of the House but also for the people who work for and with us.
