For clarification, the article quite clearly states in its first line that a government official stated that the Prime Minister's Office is cutting off communications with officials affiliated with Navigator while the federal watchdog of lobbying looks into the practices of the plugged-in firm. So it's quite clear what that statement by a government official and the PMO's decision relating to it are, that they are under investigation. This brings me to the second point.
If the leak did not occur from among your professional staff, from your offices, then more worrisome is where did it occur? How did the information get to the PMO? The only other potential source is the company that's being investigated. With today's news reports, will you be investigating to find out whether or not a company that is under investigation, that gives the heads-up to the PMO...that their relationship is under investigation? Would that now entail a part of your investigation of this particular company and its lobbying?
