As MPs head behind closed doors for their weekly party caucus meetings, questions continue to swirl around what appears to be an unprecedented public spat between Prime Minister Stephen Harper and Chief Justice Beverley McLachlin over the now-mooted appointment of former Quebec federal court judge Marc Nadon to the highest court in the land.

Meanwhile, Democratic Reform Minister Pierre Poilievre's controversial bid to rewrite Canada's election laws is back in the House of Commons spotlight as report stage debate on the now-amended bill — plus an additional 145 amendments submitted by opposition members — gets underway this afternoon.

Finally, the latest findings from Auditor General Michael Ferguson on prisons, pensions and employment statistics will likely continue to drive debate on the Hill — as will his open-ended response on launching a full investigation into the embattled Temporary Foreign Workers Program.

Kady O'Malley will be taking your questions and comments on all the major political stories of the day at noon ET.
