  We propose two schemes for the lepton mixing matrix $U = U_l^\dagger U_\nu$,
where $U = U_l$ refers to the charged sector, and $U_\nu$ denotes the neutrino
diagonalization matrix. We assume $U_\nu$ to be CP conserving and its three
angles to be connected with the Cabibbo angle in a simple manner. CP violation
arises solely from the $U_l$, assumed to have the CKM form, $U_l\simeq V_{\rm
CKM}$, suggested by unification. Oscillation parameters depend on a single
parameter, leading to narrow ranges for the "solar" and "accelerator" angles
$\theta_{12}$ and $\theta_{23}$, as well as for the CP phase, predicted as
$\delta_{\rm CP}\sim 1.3\pi$.
