Recent NA48 results on semileptonic and rare kaon decays. Measurement of   Vus
  The new results of investigation of K^0_Le3 and K^{\pm}e3 decays performed by NA48 Collaboration are presented. The measured branching fractions are used to extract Vus. The values of Ke3 form-factors and radiative K^0_Le3\gamma branching ratio are reported. A list of recent NA48 results concerning some rare neutral kaon decays is given.
