>Percentage of market share is not a clear indication of monopoly

True, and the reason is that a 30% UK-wide or a 50% Europe-wide market share can easily turn out to be a 100% market share in many local markets. Tesco defended itself by saying that 98% of consumers have access to five different super market chains within a drive time radius of 30 minutes. Make that a more realistic 10 minutes and the picture changes dramatically.
