  Starting out from the most general, gauge invariant and renormalizable scalar
potential of the R-parity violating MSSM and performing a calculable rotation
to the scalar fields we arrive at a basis where the sneutrino VEVs are zero.
The advantage of our rotation is that, in addition, we obtain diagonal soft
supersymmetry breaking sneutrino masses and all potential parameters and VEVs
real, proving that the MSSM scalar potential does not exhibit spontaneous or
explicit CP-violation at tree level. The model has five CP-even and four CP-odd
physical neutral scalars, with at least one CP-even scalar lighter than M_Z. We
parametrise the neutral scalar sector in a way that resembles the
parametrisation of the R-parity conserving MSSM, analyze its mass spectrum, the
coupling to the gauge sector and the stability of the potential.
