Abstract	The ratio $\Phi\rightarrow K^+K^-/K^0\bar K^0$ is discussed and its present experimental value is compared with theoretical expectations. A difference larger than two standard deviations is observed. We critically examine a number $9 of mechanisms that could account for this discrepancy, which remains unexplained. Measurements at DA$\Phi$NE at the level of the per mille accuracy can be presently expected to clarify whether there exist any anomaly.
