Let X = d v p and Y = d w q be Lorentz sequence spaces. We investigate when the space K X Y of compact linear operators acting from X to Y forms or does not form an M-ideal (in the space of bounded linear operators). We show that K X Y fails to be a non-trivial M-ideal whenever p = 1 or p > q. In th

We characterize those BANACH spaces X for which K(X 0, X) is an M-ideal in L(X 0, X) by means of a variant of the compact metric approximation property. As a consequence we obtain that such a space X must be hereditarily P-rich.
