Located opposite room I, this room also opens directly off the Council Chamber through double doors of bronze.

The decor was commissioned from the celebrated French interior designer Jules Leleu and is thus usually known as the "French Room" or "Leleu Room". The dominant colours are beige, a whole palette of reds - from salmon pink to wine red - golden-brown and black. Glass engravings by Anatole Kasskoff, Leleu’s chief draughtsman, form a large panel comprising 40 mirror panes depicting young women playing with doves and gathering laurel leaves. The panel is supported on a sideboard of Rio rosewood with three mirrored doors engraved with floral designs.

Kasskoff’s work is reflected in the mirrors occupying the space directly opposite, between the two windows. The motifs of the wall panel are picked up in the glass top of the round occasional table, also by Kasskoff. Around the table, which was originally in the centre of the room, are six chairs, the backrests of which are decorated with the League of Nations monogram surrounded by laurel leaves. The furnishings comprise one suite of sofas, armchairs and chairs in red velvet and a second suite in pink velvet, a rectangular table, two rectangular occasional tables and, on the floor, four carpets by Ivan Da Silva Bruhns supplied by the Leleu workshop.

The lighting deserves special mention, for it is original and is a contributary factor in the room’s decor and warmth. Slim, elegant incandescent tubes were suspended from the ceiling, and these were replaced in the 1960s by fluorescent tubes. There are also eight wall lamps of alabaster and bronze from the workshops of Jean Perzel in Paris.
