In recent years, significant experimental indications that point towardsLepton Flavour Universality violating effects in B-decays, involving $b \to c\tau \nu$ and $b \to s \ell^+ \ell^-$ have been accumulated. A possible NewPhysics explanation can be sought within the framework of R-parity violatingSupersymmetry, which contains the necessary ingredients to explain theanomalies via both leptoquark, tree-level exchange and one-loop diagramsinvolving purely leptonic interactions. In addition, an approximate $U(2)^2$flavour symmetry, that respects gauge coupling unification, successfullycontrols the strength of these interactions. Nevertheless strong constraintsfrom leptonic processes and $Z$ boson decays exclude most of the relevantparameter space at the $2 \sigma$ level. Moreover, R-parity violation deprivesSupersymmetry of its Dark Matter candidates. Motivated by these deficiencies,we introduce a new gauge singlet superfield, charged under the flavour symmetryand show that its third-generation, scalar component may participate in loopdiagrams that alleviate the above-mentioned tensions, while at the same timereproduce the observed relic abundance. We obtain a solution to both anomaliesthat is also fully consistent with the rich Flavour and Dark Matterphenomenology. Finally, we assess the prospect to probe the model at futureexperiments.
