Canadian Prime Minister Justin Trudeau, trying to revive his election campaign after the emergence of embarrassing photos, on Wednesday used a televised debate to accuse his main rival of seeking to reopen the debate on abortion.

Polls suggest Trudeau’s left-leaning Liberals could lose power to the opposition Conservatives of Andrew Scheer on October 21 amid voter unhappiness with images of Trudeau in blackface as well as a number of other scandals.

Trudeau, speaking during a French-language debate in the province of Quebec, suggested Scheer would be open to reviving the debate on abortion. There are few restrictions on abortion in Canada and the Conservatives have traditionally steered clear of the topic, fearing they could alienate progressive voters.

The other two leaders in the debate hosted by private channel TVA Jagmeet Singh of the left-leaning New Democrats and Yves-Francois Blanchet of the separatist Bloc Quebecois also pressed Scheer on the issue.

“We are seeing that three of us are aligned on values, the values of Quebecers, and we have a fourth, a Conservative party that is not aligned on the rights of women,” said Trudeau.
