I present results for the finite renormalization of the Cabibbo-Kobayashi-Maskawa (
CKM)
matrix induced by gluino--squark diagrams in the MSSM with non-minimal
sources of flavour violation. Subsequently I derive bounds on the
flavour--off--diagonal elements of the squark mass matrices by requiring that the
radiative corrections to
the CKM elements do not exceed the experimental values. The constraints on
the associated dimensionless quantities $\delta^{d\,LR}_{ij}$, $j>i$, are
stronger than the bounds from flavour-changing neutral current (FCNC)
processes if gluino and squarks are heavier than 500$\,\gev$. The
results imply that it is still possible to generate all observed flavour
violation from the soft supersymmetry-breaking terms without conflicting
with present-day data on FCNC processes. Therefore we reappraise the idea that onl
y $Y^q_{33}$
is different from zero at tree-level and all other Yukawa couplings are generated
radiatively. This model solves the SUSY flavour as well as the SUSY CP problem. The
presented results are published in \cite{Crivellin:2008mq}.
