A few months ago but only made public today, Archduke István of Austria has resigned from his position as secretary general of the administration of the Grand Duke. The son of the late Archduke Felix, son of Blessed Emperor Karl, and his wife née Princess Anne Eugénie of Arenberg had held the position since 2009 before being replaced by Christian Billon sometime last year. Archduke István, who holds a bachelor's degree in law and a master's degree in business administration, and his family have been living in the Grand Duchy for many years. To the best of my knowledge, his main occupation is as a private employee of an electronic component manufacturer in Luxembourg.
Other changes to the Grand Ducal staff include Guy Schmit who became the director of the Fondation du Grand-Duc et de la Grand-Duchesse.
