That's a bit vague. You say you think you heard rumours before, but that ultimately, the first time you really heard about it was from Mr. Marques.
I'm trying to understand. Mr. Marques says he took the initiative to go and talk to Michael Wernick, who then went to Janine Sherman. That might have some logic to it, because he could have said that he was mandated as an advisor, that he took extra steps. However, at the end of the day, the person who makes the decisions in the Prime Minister's Office is the chief of staff, so that is you.
How could Mr. Marques have made this decision without being ordered to do so by you?
