Anonymous senior Conservatives are apparently agitating for Helena Guergis to be swiftly dispatched to the furthest reaches of the government backbenches. Make of this what you will.
Keep in mind that, if memory serves, no minister in the Harper government has been outright fired or banished. Michael Chong resigned as minister of intergovernmental affairs in opposition to the Quebecois motion. Maxime Bernier resigned after misplacing his briefs. Various ministers perceived to be underperforming (Gordon O’Connor, Rona Ambrose, Lisa Raitt) have been moved to less-prominent portfolios, but only in the context of a cabinet shuffle. No one, if I recall correctly, has ever been outright and unambiguously fired.
