Query: Neutralino Relic Density with a Cosmological Constant confronts
  Electroweak Precision Measurements   We discuss the relic density of the lightest of the supersymmetric particles
({\small LSP}) in view of new cosmological data, which favour the concept of an
accelerating Universe with a non-vanishing cosmological constant. The new bound
on the Cold Dark Matter density, $\Omega_{\mathrm{CDM}} h_0^2 \lesssim 0.22$,
puts stringent constraints on supersymmetry preferring low supersymmetry
breaking scales, in sharp contrast to electroweak precision measurements
favouring large supersymmetry breaking scales. Supersymmetric predictions are
in agreement with cosmological data and electroweak precision data in the
window of the parameter space: $m_0<200\GeV$, $300\GeV<M_{1/2}<400\GeV$,
putting bounds on sparticle masses, which may be evaded if $m_{LSP}
<m_{{\tilde{\tau}}_R} \lesssim 1.2 m_{LSP}$.
