  We examine the processes $e^+ e^-\longrightarrow W^+ W^-$ and $Z^0 Z^0$ in
the context of the $SP(6)_L\otimes U(1)_Y$ model. We find that there are
significant deviations in the total cross sections $\sigma (s)$ from the
standard model results due to the presence of additional gauge bosons
$Z^\prime$ and $W^\prime$ in the model. These deviations could be detected at
LEP.
