The Commission shall take appropriate measures to ensure that, when actions financed under this Regulation are implemented, the financial interests of the Union are protected by the application of preventive measures against fraud, corruption and any other illegal activities, by effective checks and, if irregularities are detected, by the recovery of the amounts wrongly paid and, where appropriate, by effective, proportionate and dissuasive administrative and financial penalties.

The Commission shall be responsible for the supervisory controls with regard to the European Solidarity Corps actions managed by the national agencies. It shall set the minimum requirements for the controls by the national agency and the independent audit body.

National agencies shall be responsible for the primary controls of grant beneficiaries for the actions of the European Solidarity Corps which are entrusted to them. Those controls shall be proportionate and adequate and give reasonable assurance that the grants awarded are used as intended and in compliance with the applicable Union rules.

With regard to the funds transferred to the national agencies, the Commission shall ensure proper coordination of its controls with the national authorities and the national agencies, on the basis of the single audit principle and following a risk-based analysis. This paragraph shall not apply to investigations carried out by the European Anti-Fraud Office (OLAF).
