1. Enforcement authorities taking part in the coordinated action shall ensure that they conduct investigations and inspections in a timely, effective and coordinated manner. Enforcement authorities shall seek to conduct investigations and inspections and, to the extent that national law so allows, to apply interim measures simultaneously with those of other enforcement authorities. 2. Enforcement authorities taking part in the coordinated action shall set out in a common statement the outcome of the investigation and the assessment of the widespread unfair trading practice with a cross-border dimension, summarising the national measures taken and, where applicable, the different opinions of the enforcement authorities. 3. Without prejudice to the rules on confidentiality and on trade secrecy laid down in Directive (EU) 2016/943 of the European Parliament and of the Council, the enforcement authorities concerned by the coordinated action shall publish the common statement referred to in paragraph 2 of this Article or parts thereof on their websites and inform the Commission of the publication.
