Former Formula One champion Jacques Villeneuve says he received threats after blasting Quebec's student movement.

The Canadian driver said Friday he received "dangerous" emails in reaction to his comments Thursday night after protesters tried to disrupt a cocktail party kicking off Canadian Grand Prix festivities.

Villeneuve was instantly catapulted into a starring role in a four-month dispute that has made international news. With Quebec celebrities mainly remaining silent or lining up behind the protesters, the driver was suddenly the movement's most famous, most virulent critic.

He also said if protesters make good on a plan to jam the Montreal subway system Sunday before the race, it will amount to domestic terrorism.
