Langlois noted that the police were not going to join "yellow vest" protesters, however, intended to support them.
"We will go to the rally with our banners to show that we support the demand to increase the purchasing power. Any police officer not on duty has the right to join them during the demonstration," Langlois said.
Langlois also added that the French security services were powerless in confronting "yellow vest" protesters, as former French President Nicolas Sarkozy had significantly undermined their capabilities by focusing on counterterrorism activities. According to the secretary general, the French authorities should meet some of the demands of "yellow vest" protesters in order to stabilize the situation.
The so-called "yellow vest" protests, named after the reflective vests all French drivers are required to keep in their cars, have been ongoing in France since November 17. Diesel prices in France have risen by around 23 percent since the beginning of the year, while the gasoline prices have gone up by 15 percent. On Wednesday, French President Emmanuel Macron announced that he was abandoning a proposed fuel tax hike following violent protests.
