A transitive permutation group is called semiprimitive if every normal subgroup is either transitive or semiregular. This class of groups includes all primitive, quasiprimitive and innately transitive groups.

They have received recent attention due to a conjecture of Potočnik, Spiga and Verret that generalises the Weiss conjecture for locally primitive graphs. In this talk I will discuss recent work with Luke Morgan that develops a general theory for the structure of semiprimitive groups and give some applications of the new theory.
