Advisory Committee for the Coordination of Fraud Prevention (COCOLAF)

COCOLAF coordinates how the European Commission and its Member States go about combatting fraud involving EU money.

The participants are representatives from the competent national services of the Members States and from Commission services. It is managed by OLAF on the Commission’s behalf.

The Commission is represented in the Committee by:

  • OLAF
  • The Commission services responsible for the revenue side of the EU budget (DG BUDG, DG TAXUD)
  • The Commission services responsible for shared management funding
  • Other horizontal services (DG GROW, Legal Service, etc.).

There are also expert groups for different policy areas. These groups:

  • stimulate cooperation among specialised national fraud prevention services
