The branching ratio of the lepton to a neutral kaon meson is measured from a sample of approximately 200,000 decays recorded by the OPAL detector at centre-of-mass energies near the Z0 resonance. The measurement is based on two samples which identify one-prong decays with and mesons. The combined branching ratios are measured to be
where the first error is statistical and the second systematic.
