## Abstract

The branching ratios of the τ^{-}→h^{-}h^{+}h^{-}v_{ τ} and τ^{-}→h^{-}h^{+}h^{-}≥1π ^{0}v_{τ} decays, where h is either a charged π or K meson, are measured using a data sample of 87861 τ^{+}τ^{-} pairs collected with the OPAL detector at LEP. The two branching ratios are extracted simultaneously from a sample of three charged particle decays and found to be: {Mathematical expression} where the first error is statistical and the second systematic. The branching ratio of the τ lepton into three charged particles is measured to be: {Mathematical expression}
