The Welsh Assembly Government host the European auditors annual meeting in Cardiff.

The event is an opportunity for auditors from the European Commission, European Anti-Fraud Office, European Court of Auditors and the Member States to share experience and knowledge with the aim of ensuring that investments financed by the EU's Cohesion Policy are used effectively and efficiently.

Member States have primary responsibility for preventing and correcting errors, as well as tackling rare cases of fraud. The European Commission has overall responsibility for the EU budget and can suspend payments or impose corrections to claw back undue payments even when 99% of cases are errors rather than real fraud.

The "Homologues' Group" meeting has taken place annually since 1991. The participants consist of representatives from the national control bodies of the 27 Member States. The European Commission audit services for the Structural Funds, the European Anti-Fraud Office (OLAF) and the European Court of Auditors also take part.
