Arguments are given that the lightest supersymmetric particle should be a neutralino {chi}. Minimizing the fine tuning of the gauge hierarchy favours {omega}{sub {chi}}h{sup 2}{approx}0.1. There are important constraints on the parameter space as the MSSM from the stability of the electroweak vacuum. Co-annihilation with the next-to-lightest supersymmetric particle is potentially significant. Incorporating the latest accelerator constraints from LEP and elsewhere, we find that 50 GeV < or approx. m{sub {chi}} < or approx. 600 GeV and tan {beta} > or approx. 2.5. if soft supersymmetry breaking parameters are assumed to be universal.
