Abstract
Between 1990 and 2001, the CLEO II/II.V/III detectors at the Cornell Electron Storage Ring (CESR) have recorded over of 34 million B decays and nearly 60 million charm decays. A selection of the latest results in the electroweak sector from these data sets has been presented. The focus is placed on the determination of the CKM matrix elements Vub, and Vcb, and how the measurement of the b to s gamma photon spectrum can be used to reduce theoretical uncertainties.
