Search for charginos and neutralinos are presented, based on the data samples recorded in 1999 and 2000 by the DELPHI detector at centre-of-mass energies from 192 to 209 GeV. No evidence for a signal was found. The lower chargino mass limits are 5-6 GeV /c2 higher than those obtained at a centre-of-mass energy of 189 GeV. The (μ, M 2) MSSM domain excluded by combining the chargino searches with neutralino searches at the Z resonance implies a limit on the mass of the lightest neutralino which, for a heavy sneutrino, is constrained to be above 37.6 GeV /c2 for tan β≥1. Upper limit at 95% CL on the neutralino production cross-section times branching fraction are derived.
