The ratio of charged kaon leptonic decay rates RK=BR(K --> e nu)/BR(K --> mu nu) is strongly suppressed and predicted to an excellent precision within the Standard Model. It therefore has a unique sensitivity to deviations from lepton universality arising in multi-Higgs new physics models, including SUSY. A new measurement of RK based on the full dedicated data sample collected by the NA62 experiment at CERN in 2007 is reported. The record accuracy of 0.4% constrains the parameter space of models with extended Higgs sector.
