On the subject of the e-mails to which you refer, I will begin by saying something I said before, which is that it's the mandate of the Privy Council Office to provide professional non-partisan advice and support to the government.
It's not our job to provide advice on personal or political matters to our ministers' offices and it would be highly unusual for PCO to have records on personal or political matters. So to answer your question, yes, whenever we receive an ATIP request, I have an ATIP division that coordinates the work around that and makes sure that the delegation instrument that is in place is implemented in the response to each and every request and that we follow the rules that the legislation, interpreted by court decisions, has set out for us.
