Canadian Prime Minister Justin Trudeau wore “brownface” at a private school gala nearly two decades ago, a photo obtained by Time Magazine shows.
Addressing the image, Mr Trudeau said he “deeply regretted” his actions and “should have known better”.
The 2001 yearbook picture shows Mr Trudeau with skin-darkening make-up on his face and hands at the West Point Grey Academy in Vancouver.
The prime minister is battling for re-election on 21 October.
Mr Trudeau, who is the son of late former Prime Minister Pierre Trudeau, used to teach at the elite academy.
Speaking to journalists after the Time article was published, Mr Trudeau said that he was dressed in the photo in an Aladdin costume at an Arabian Nights-themed gala.
He admitted that the photo was racist and said he recognised he “shouldn’t have done it”.
