We consider partial supersymmetry breaking in N=2 supergravity coupled to a single vector and a single hypermultiplet. This breaking pattern is in principle possible if the quaternionKähler space of the hypermultiplet admits (at least) one pair of commuting isometries. For this class of manifolds, explicit metrics exist and we analyse a generic electromagnetic (dyonic) gauging of the isometries. An example of partial breaking in Minkowski spacetime has been found long ago by Ferrara, Girardello and Porrati, using the gauging of two translation isometries on SO(4, 1)/SO(4). We demonstrate that no other example of partial breaking of N = 2 supergravity in Minkowski spacetime exists. We also examine partialbreaking vacua in antide Sitter spacetime that are much less constrained and exist generically even for electric gaugings. On SO(4, 1)/SO(4), we construct the partiallybroken solution and its global limit which is the AntoniadisPartoucheTaylor model.
