Speaker Greg Fergus kicked Conservative Leader Pierre Poilievre out of the question period Tuesday after a particularly nasty exchange with Prime Minister Justin Trudeau.<br /><br />Poilievre's day-long removal from the House of Commons came after he called Trudeau a "wacko" for supporting B.C.'s past policy of decriminalizing some hard drugs in an attempt to reduce the number of overdose-related deaths.<br /><br />Poilievre said it was a "wacko policy" backed by "this wacko prime minister." Fergus asked him to withdraw the "unparliamentary language."<br /><br />Poilievre refused, saying only that he agreed to replace "wacko" with "extremist" or "radical." Poilievre's refusal prompted Fergus to remove him.<br /><br />"There are a couple of things that are going on here today that are not acceptable," Fergus said.<br /><br />He later called it a "remarkable question period" after MPs from all sides yelled at one another and called each other names.<br /><br />Following Poilievre's removal, the Conservative caucus left the Commons chamber en masse, following their leader.<br /><br />Trudeau fielded a few more questions Tuesday from Bloc and NDP MPs and then left the chamber after the fracas.
