While French labor activists have frequently timed noisy demonstrations or strikes to take place during the Cannes Film Festival in their bids for maximum exposure, police have effectively maintained order during them. Now it is the police themselves who are planning to stage a strike during the festival. The BBC reported Wednesday that a two-hour strike, set to take place on May 19 -- two days after the festival opens -- could disrupt security arrangements for the numerous high-profile guests expected to attend on that day. The police demonstration is scheduled to take place outside the event's main venue, the Palais de Festivals. A second walkout could occur four days later.
