Proportional representation is generally regarded as being the “fairest system” on the grounds that it tends towards a more faithful representation of the various political forces. However, the drawback with this system is that it favours a fragmentation of those seeking to be elected and consequently makes it more difficult to form stable majorities in the assemblies. This was shown by the Polish legislative elections of June 1993: 29 parties were represented in the lower house (460 members in all), but no party obtained more than 12.3% of the seats.
