The determinations of |V{sub ud}|{sup 2} with super-allowed Fermi {beta} decay in nuclei and of the weak charge of cesium in atomic parity violation deviate from the standard model predicitions by 2{sigma} or more. In both cases, the standard model overpredicts the magnitudes of the relevant observables. I discuss the implications of these results for R-parity violating (RPV) extensions of the minimal supersymmetric standard model. I also explore the possible consequences for RPV supersymmetry of prospective future low-energy electroweak measurements. (c) 2000 The American Physical Society.
