Ottawa: Canadian Prime Minister Justin Trudeau's brownface picture scandal has deepened as other images of him emerged wearing dark make-up only hours after he had apologised for what he characterised as a racist act at a 2001 costume party.

With less than five weeks to go before a national election, Time magazine published a picture of him on Wednesday in brownface from an "Arabian Nights" party when he was a 29-year-old teacher at a private school in Vancouver.

Justin Trudeau has apologised after this photo emerged showing him in brownface makeup at an 'Arabian Nights' costume party in 2001.

During his apology, he also admitted to performing "Day O", a traditional Jamaican song made famous by Harry Belafonte, in brownface during a high school talent show years earlier. The Canadian Broadcasting Corp then published a picture from that performance that was confirmed as authentic by a spokeswoman.

On Thursday morning, local time, more damaging material surfaced. Trudeau’s campaign spokeswoman, Zita Astravas, confirmed that a video posted by GlobalNews, a Canada-based news organisation, showed the Prime Minister in the early 1990s wearing dark make-up and an Afro wig. In the video, he is waving his hands around and sticking out his tongue.
