The Belgian princess Delphine made her first appearance on the King's Day of Belgium.

The illegitimate daughter of the former King Albert II appeared with the royal family on the Belgian national holiday.

She was recognized as a princess last year after a long legal battle.

Belgium invariably celebrates its national holiday with a parade in the capital Brussels.

That is taken by King Philip, Delphine's half-brother.

The ceremony this year is a lot more bare and sober than usual.

The army and other services still have their hands full in Wallonia, which has been hit hard by floods.

Crown Princess Elisabeth did march past the royal gallery with her parents and other family.

She completed military training last year.

Elisabeth's aunt Claire, the wife of Prince Laurent, was absent from the celebration.

Belgian media report that the two may be heading for a divorce.
