Jack de Vries, former personal advisor and campaign strategist of Dutch Prime Minister Jan Peter Balkenende was sworn in as State Secretary of Defense on Tuesday, Dutch media reported Wednesday.
De Vries, 39, takes over from Cees van der Knaap, who served as mayor of the central Dutch city of Ede.
De Vries was sworn in at the royal Huis ten Bosch Palace in The Hague by Queen Beatrix.
De Vries was advisor to the Christian Democratic Alliance (CDA)from 1997 to 2001. He quit the job when CDA leader Jaap de Hoop Scheffer stepped down. De Vries was reappointed adviser and spokesperson by Balkenende when the latter became party leader in 2002.
De Vries was the organizer of several CDA election campaigns, including last November's general elections that enabled the CDA to retain its parliamentary majority.
