000002738 520__ $$aSemileptonic B decays allow measurements of the magnitudes of the CKM matrix elements V_cb and V_ub, thus providing access to fundamental parameters of the theory. Thanks to the low-background collision environment along with the possibility of partially or fully reconstructing one of the two B mesons in the event, Belle II is expected to greatly improve the precision on these parameters, using both inclusive and exclusive techniques. The latest results and prospects will be presented. In addition, measurements of the CKM unitarity triangle angles, which parameterize CP violation in the standard model, will be discussed.
