The prefect of Yvelines Jean-Jacques Brot will leave office in March. This atypical senior civil servant, with an unclassifiable style, will have led the prefecture since April 2018.

He will be replaced by Frédéric Rose, current security advisor to President Emmanuel Macron. The former advisor to Jacques Chirac quickly distinguished himself by his unusual style in a profession marked by a sometimes pathological reserve. The 68-year-old cultivated both high-ranking friendships and other, more discreet ones, with modest personalities.
