House of Commons Speaker Anthony Rota has resigned amid international controversy over his recognition of a Ukrainian war veteran who fought in a Nazi unit.

Rota announced his resignation in the House of Commons Tuesday afternoon. His resignation takes effect at the end of the sitting day Wednesday, he added.

Senior Liberals, the NDP, the Bloc Québécois and Conservative Leader Pierre Poilievre all urged Rota to resign after he brought 98-year-old Ukrainian Canadian Yaroslav Hunka to Parliament Hill for Ukrainian President Volodymyr Zelenskyy’s visit to Ottawa on Sept. 22.

“I must step down as your Speaker. I reiterate my profound regret for my error in recognizing an individual in the House,” Rota said.
