The ratio of binaries among the WR stars is subject of many discussions essentially due to two reasons: First, the important role that the presence of a companion can play in the evolution of a massive star and as consequence in the interpretation of the evolutionary phase of the WR stars. Second, the strong difficulty to determine the binarity of the WR stars due to the width of the spectral lines.
