We present the results of an extensive analysis of flavour physics in both
quark and lepton sectors, in the Littlest Higgs model with T-parity (LHT). In
the quark sector, we identify some interesting scenarios for new mirror quark
masses and V_Hd mixing matrix that satisfy the existing experimental
constraints from K and B physics and simultaneously allow large New Physics
effects in rare decays and CP-violating observables. In the lepton sector,
where flavour violation in the Standard Model is highly suppressed by small
neutrino masses, LHT effects turn out to be naturally huge and could be seen in
the near future measurements of lepton flavour violating decays.Comment: Contribution to the proceedings of HQL06, Munich, October 16th-20th
