I will give you a short answer and then turn it over to André, who is the deputy clerk of procedure. In fact, I think in the House of Commons, we have actually built quite a deep pool of talent. For recruitment purposes, we tend to select people from inside. In fact, it's a way to acknowledge the work done by those who want to make a career here and advance over the course of a number of years.
I'll let André finish with a more comprehensive reply.
