Popis:	We show the Jordan property for regional fundamental groups of klt singularities of fixed dimension. Furthermore, we prove the existence of effective simultaneous index one covers for $n$-dimensional klt singularities. We give an application to the study of local class groups of klt singularities. Comments are welcome. v2: final accepted version. To appear in Geometry & Topology. Only minor changes, corrected typos, updated bibliography. 24 pages; v1: 24 pages
