Canadian Prime Minister Justin Trudeau, a supporter of feminist causes, on Thursday conceded for the first time that he had apologized in 2000 to a woman who accused him of groping her but insisted he did not feel he had done anything wrong.

Trudeau, whose government is working on new legislation against workplace harassment, has faced Canadian media scrutiny in recent weeks about what happened at a charity fundraiser in Creston, British Columbia nearly 20 years ago.

In his first direct comments on the incident on Canada Day last Sunday, the prime minister said he "didn't remember any negative interactions that day at all" but on Thursday he said "I apologized in the moment" without giving details.
