  We discuss how slip conditions for the Stokes equation can be handled using
Nitsche method, for a stabilized finite element discretization. Emphasis is
made on the interplay between stabilization and Nitsche terms. Well-posedness
of the discrete problem and optimal convergence rates, in natural norm for the
velocity and the pressure, are established, and illustrated with various
numerical experiments. The proposed method fits naturally in the context of a
finite element implementation while being accurate, and allows an increased
flexibility in the choice of the finite element pairs.
