The data collected by DELPHI in 1998 at the centre-of-mass energy of 189~GeVhave been used to update the search for charginos nearly mass-degenerate withthe lightest supersymmetric particle, which is assumed to be the lightest neutralino. Mass differences below $\Delta M\!=\!3$~GeV/c$^2$ are considered.No excess of events with respect to the Standard Model expectation has beenobserved, and exclusions in the plane of $\Delta M$ versus chargino mass are given. The new $\Delta M$ independent lower limit on the mass of the charginois $62.4$~GeV/c$^2$ in the higgsino scenario (which includes the gaugino massunification scenario), if all sfermions are heavier than the lightest chargino.In the approximation of large sfermion masses the limit is $5...
