We report on recent searches for lepton flavour violating decays of the {tau} lepton: {tau}{sup -} {yields} {ell}{sup -} K{sub S}{sup 0}, {tau}{sup -} {yields} {ell}{sup -}({rho}{sup 0}, K*{sup 0}, {bar K}*{sup 0}, {phi}). These preliminary results use data samples collected by the BaBar detector at the SLAC PEP-II B factory corresponding to integrated luminosities of 469 fb{sup -1} for the {tau}{sup -} {yields} {ell}{sup -}K{sub S}{sup 0} and 451 fb{sup -1} for the {tau}{sup -} {yields} {ell}{sup -}({rho}{sup 0}, K*{sup 0}, {bar K}*{sup 0}, {phi}) searches. No statistically significant signal has been observed in any of these channels and we set upper limits on their branching fractions between 0.8-18.2 x 10{sup -8} at 90% confidence level.
