Abstract
We demonstrate that the R-parity breaking interactions within their current experimental upper bounds can give rise to large mixing-induced CP asymmetry in exclusive radiative B decays that may be detectable in the upcoming B factories.

9 pages, Latex, requires axodraw.sty; in v2 two more PS figs included and more discussion on how our prediction of large CP asymmetry is consistent with the constraints from b \to s \gamma rate
