  We report on a simple calculation of the magnetotransport in cuprate
superconductors, based on the nearly antiferromagnetic Fermi liquid (spin
fluctuation) model. We find that the model explains all important features seen
experimentally: the violation of K"ohler's rule, the close relationship between
the Hall angle and the magnetoresistance, the temperature dependence of the
first high field correction to MR and the doping dependence of the low field MR
data. In addition, the estimated values of omega_c tau, calculated using
parameters obtained from the NMR measurements, yield values in close agreement
with those found experimentally for overdoped and optimally doped cuprates.
