Stephen Harper is losing his famously reclusive right-hand man. Guy Giorno, who has served as Harper’s chief of staff since July 2008 will reportedly leave the job before the end of year. The news of Giorno’s departure comes as the Conservatives are struggling to regain their footing after recent scandals over the census, Afghan detainees, the gun registry, and other issues. Giorno, a former top adviser to Mike Harris during the Progressive Conservative premier’s reign in Ontario, was often accused of engaging in sharply divisive politics, though he’s also been credited as the architect behind the federal government’s “Economic Action Plan” and with imposing a disciplined approach inside the PMO. His departure was reportedly motivated by the recent birth of his second child.
