We show that the effect can be very large despite the very strong constraints on quark flavour violation (QFV) from experimental data on B mesons. We find that the two lightest up-type squarks ${\\tilde u}_{1,2}$ can have large branching ratios for the decays into $c {\\tilde\\chi_1^0}$ and $t {\\tilde\\chi_1^0}$ at the same time, leading to QFV signals '$p p \\to c \\bar t\\, (t \\bar c)$ + missing-$E_T$ + $X$' with a significant rate.
