Prospective NDP leadership candidate Yves Engler has history of confronting politicians in the street

The latest entrant in the race to lead the federal New Democrats is a long-time activist who has confronted and filmed cabinet ministers and MPs in the street and is due to stand trial this month for allegedly harassing a police officer.

Yves Engler, a self-described “political activist agitator,” announced last week that he had formally submitted a nomination package after spending months campaigning, holding meetings and raising money toward the $100,000 entry fee.
