OTTAWA -- Conservative Leader Erin O鈥橳oole is defending his decision to remove Sen. Denise Batters from his party鈥檚 caucus after she started a petition calling for an expedited review of his leadership, calling it 鈥渘ecessary,鈥 while Batters said the move 鈥渟peaks volumes鈥 about O鈥橳oole.

鈥淵ou don't want to make that decision, but really she made it for herself,鈥 O鈥橳oole said Wednesday, on his way into a caucus meeting focused on preparing for the return of Parliament.

鈥淲e have to have all members of the team focused at that, and it was a necessary decision to make for the well-being of our caucus, of our Parliament, and of the country,鈥 he said.

In a statement issued Wednesday morning, Batters said she is, and 鈥渁lways will be a Conservative,鈥 but said that the current leader 鈥渃annot tolerate criticism.鈥

鈥淎fter the election, I raised my concerns with Mr. O鈥橳oole directly. He did not respond and he did not act. I then asked publicly that our members have a voice. His response now is to kick me out,鈥 she said.

鈥淚f Mr. O鈥橳oole is certain that the members of our party support the new direction in which he is taking our party, he should have nothing to fear by facing our members democratically in an expedited confidence vote. That he is fighting against this with threats and intimidation to caucus speaks volumes,鈥 said Batters.

On Monday, the Stephen Harper-appointed Saskatchewan senator launched what quickly became a contentious petition, taking the position that Conservative members should be able to vote within the next six months rather than in 2023 on the direction of the party and whether O鈥橳oole should remain the leader.

In unveiling the call for signatures, Batters said that O鈥橳oole 鈥渓ost this election by every measure,鈥 and was critical of his 鈥渇lip-flopped鈥 positions on policies including guns and the carbon tax.

Within hours, Conservative Party President Rob Batherson was , saying the effort was in contravention of party policies and procedures, and O鈥橳oole supporters within caucus were quick to offer their backing, calling on Batters to back away from the petition. 

Batters, who has been critical in the past of the current leader, has not been the only party-loyal parliamentarian to speak out about O鈥橳oole鈥檚 leadership and 2021 election performance, but has been the only member removed over it.

Asked why Batters was removed and others were not, including Nova Scotia Conservative Sen. Michael MacDonald who also called on his colleagues to advance an early leadership review, O鈥橳oole didn鈥檛 directly answer.

鈥淲e've had two very, very good national caucus meetings, some going as long as six hours and we've united on our way forward as a team. People that are now allowing their frustrations and their own personal agendas, or issues on the pandemic to interfere with our progress are not part of the team,鈥 O鈥橳oole said.

Batters called it a 鈥渄ouble standard,鈥 and is continuing to , which she said has support from MPs. While no current MPs have publicly backed Batters鈥 calls, she鈥檚 cited fears of 鈥渞epercussions鈥 for doing so as being part of the reason she, as a senator, decided to spearhead the latest leadership challenge.

In October, the Conservative Party suspended a national council member from Ontario, Bert Chen, after he lead an effort to trigger an early leadership review by starting an online petition that also requested that the leadership question be put to members before 2023.

As it stands, O鈥橳oole is set to face a leadership review at the party鈥檚 next convention, which is scheduled for 2023.

In October, the caucus voted to give themselves the power to begin an earlier leadership review process. This would require 20 per cent of caucus signing a formal agreement to trigger the review, and then it would require a majority of caucus members to vote to remove the leader through a secret-ballot process. So far, that action has not been taken.

On their way in to Wednesday鈥檚 meeting, a handful of Conservative MPs spoke to reporters about their support for their leader.

鈥淢r. O'Toole has only been leader for just over 14 months. The members just had their say, and I don't think it's productive at all to be taking leaders out after 14 months of being leader without giving Canadians an opportunity to get to know them and again, trust them,鈥 said Manitoba MP Marty Morantz.

The day after the election, O鈥橳oole announced he would be initiating an internal review of what went wrong during the 2021 election campaign. When he announced the review, he said the party was "building towards victory next time.鈥

Former Alberta MP James Cumming is chairing that review process, which O鈥橳oole said will 鈥渋deally鈥 be completed by the end of the year, but has not committed to making the review鈥檚 findings public.
