(27) National monitoring systems such as national rapporteurs or equivalent mechanisms should be established by Member States, in the way in which they consider appropriate according to their internal organisation, and taking into account the need for a minimum structure with identified tasks, in order to carry out assessments of trends in trafficking in human beings, gather statistics, measure the results of anti-trafficking actions, and regularly report. Such national rapporteurs or equivalent mechanisms are already constituted in an informal Union Network established by the Council Conclusions on establishing an informal EU Network of National Rapporteurs or Equivalent Mechanisms on Trafficking in Human Beings of 4 June 2009. An anti- trafficking coordinator would take part in the work of that Network, which provides the Union and the Member States with objective, reliable, comparable and up-to-date strategic information in the field of trafficking in human beings and exchanges experience and best practices in the field of preventing and combating trafficking in human beings at Union level. The European Parliament should be entitled to participate in the joint activities of the national rapporteurs or equivalent mechanisms.
