  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.
