Lisa Raitt calls for Conservative leadership 'cheaters' to be expelled

Conservative leadership contender Lisa Raittis calling on the party to expel any candidate who has broken the party's rules and levy "significant" fines on their campaigns.

The call comes amid a flurry of allegations of membership fraud and vote buying and a series of barbs traded betweenthe Maxime Bernier and Kevin O'Leary camps as the race to replace Stephen Harper becomes increasingly contentious.

"Cheaters and rule breakers who do this discourage the involvement of both our long standing and new party members. It makes a mockery of their commitments and corrupts the process," Raitt said in a statement Monday. "I am deeply concerned about a leadership election process that has now been called into question."

Late last week, O'Leary called for a review of the party's membership list after he said"backroom organizers" were using prepaid credit cards to sign up "fake members."After a speedy investigation, the party struck 1,351 memberships from its voting listafter the partyfound they hadbeen purchased inappropriately.

NowBernier's team is branding O'Leary a hypocrite, claimingthey have proof that one of O'Leary's Sikh-Canadian organizers was offering to pay the membership fees of six would-be party members in Brampton, Ont.

CBC News has asked the Bernier campaign to produce the affidavitit shared with the Globe and Mail,but was rebuffed.

• Tories strike 1,351 names off membership list
• Organizers signing up 'fake members,' says O'Leary

Raitt said that since the allegations first surfaced, "all people want to discuss is this very disturbing story. We cannot let our legitimate party members be impacted by this type of behavior.

"I am calling for the expulsion of any candidate found to have broken the leadership rules and a significant fine for any campaign found to have authorized this type of activity."

She didn't name the candidate she thought had engaged in this type of activity.

The former Harper cabinet minister said the party should ensure every new membership is validated by a third party audit.

AriLasken, O'Leary's spokesperson, said everything is above board.

"Mr. Chatha has not submitted any lists or memberships in bulk to theO'Leary campaign, and has only signed up his family," he said, referring to the name of the of the Conservative Brampton-Eastriding association president who is alleged to have offered to pay for memberships.

"TheO'Learycampaign will continue to operate with transparency and by the rules," Lasken said. "Mr.O'Learycontinues to call on the party for a full audit of the entire list when it is finalized at the end of the month."

Cory Hann, a spokesperson for the Conservatives, said the party regularly reviews memberships and will ensure all rules have been followed.

Party memberships must be purchased by 5 p.m. on March 28 in order to cast a ballot in the leadership race, and all voters submitting their ballots by mail are required to send a photocopy of their photo ID.
