Quite a landslide in the Belgian Queen's entourage has happened as Mathilde's main advisor, Machteld Fostier (68) who's been with her since 1999, has retired. In September 2026, at the start of the new royal year, she will be replaced by Marleen Steenbrugghe.
A skilled and experienced diplomat, Machteld Fostier was with Mathilde from her very first days on the royal scene. For years she was the Princess's only close collaborator, they worked together daily. Wherever Mathilde went, Machteld was present - both at the office and during public activities in Belgium and abroad.
During a two year break, from 2006 to 2008, Machteld Fostier didn't work for Mathilde, but was the Belgian Head of mission in Washington. In 2009 she took up her former position again. When Mathilde became Queen in 2013, Machteld stayed in place, from then on with the title of private secretary.
Just like Mathilde, Machteld Fostier has been a very loyal and dedicated worker, a perfectionist.
Machteld Fostier will remain at Mathilde's disposal for certain special activities.
