Trudeau wary of how often he ‘blacked’ up.

Canadian Prime Minister Justin Trudeau says he is wary of being definitive about how many times he has worn brown or blackface because he did not recall the recent pictures that have surfaced.

Mr Trudeau’s election campaign is trying to contain a growing furore after a yearbook photo surfaced of him in brownface at a 2001 costume party and two other similar incidents came to light.

Canada’s Global News TV network broadcast a brief video of Trudeau in blackface while raising his hands in the air and sticking out his tongue. The network said it is not clear when and where it was taken.

Time magazine on Wednesday published a photo of the then 29-year-old Mr Trudeau wearing a turban and robe, with dark makeup on his hands, face and neck.

It was taken at a school’s Arabian Nights themed dinner.

He also acknowledged performing a blackface version of Harry Belafonte’s Banana Boat Song (Day-O) during a talent show.

The prime minister at first did not answer repeated questions about how many times he wore blackface or brownface.

He later said he did not recall the pictures.

With his bid for re-election just a month away, the 47-year-old Mr Trudeau begged Canadians to forgive him.

He said he has hurt people who thought he was an ally and it is something he deeply regrets and should not have done.

Mr Trudeau said it does not represent the person or leader he has become.

He added that he never talked about it publicly because he was embarrassed.

It could all spell more trouble for Mr Trudeau, who polls say is facing a serious challenge on October 21 from Conservative leader Andrew Scheer.

Justin Trudeau apologised for wearing blackface.
