Madam Chair, before I ask Mark to elaborate on that, we do work very closely with the Sergeant-at-Arms at the House of Commons, we do work closely with the PCO, and we do work closely with the service to make sure that the information is provided.
I can't speak on behalf of the Sergeant-at-Arms as to how frequently he talks to the MPs, but I know, from a ministerial approach, we have the liaison teams that reach out to them on a regular basis with regard to the security of a minister, and we approach the topic of interference. On a grander scale, I'll pass it over to my colleague.
