We search for lepton flavour violating couplings via doubly charged bilepton(or doubly charged Higgs) exchange in electron-positron annihilation process $\text{e}^{+}\text{e}^{-}\to \mu^{+}\mu^{-}, \tau^{+}\tau^{-}$ using CERN LEPdata at the center of mass energies between 189-207 GeV. Standard model programZFITTER has been used to calculate radiative corrections. We find that$g_{L}^{2}/M_{L}^{2}<O(10^{-6})GeV^{-2}$ at 95% C.L. for flavour violatingscalar and vector bilepton couplings.Comment: 4 Figure
