A search for pair-produced charginos and neutralinos with R-parity violating decays has been performed using a data sample corresponding to an integrated luminosity of about 700 pb^-1 collected with the OPAL detector at LEP at centre-of-mass energies up to sqrt{s}=209 GeV. The searches have been performed under the assumptions that the lightest supersymmetric particle promptly decays and that only one R-parity violating coupling is dominant for each of the decay modes considered. Such processes would yield multiple leptons, jets plus leptons, or multiple jets with or without significant missing energy in the final state. No excess of such events above Standard Model expectation has been observed. Limits are presented on the production cross-sections of the lightest chargino and the lightest neutralino, on their masses and on areas in the parameter space in the framework of the Minimal Supersymmetric Standard Model.
