House of Commons Speaker Andrew Scheer, deputy House clerk Marc Bosc and chief financial officer Mark G. Watters are scheduled to spend an hour at Procedure and House Affairs this morning as part of the annual main estimates review.
Although the ongoing controversy over the NDP's allegedly 'inappropriate' use of House resources is not on the official agenda, it's a safe bet that both the Conservatives and the New Democrats on the committee will use the subsequent question-and-answer session to further their respective lines of attack/defence.
Also scheduled to make an appearance today: Chief Electoral Officer Marc Mayrand, who will field questions on his office's projected budget during the second hour.
We'll have full liveblog coverage of the meeting at 11 a.m. ET.
