In line with Council of Europe practice, political parties, media and online platforms may consider adopting voluntary codes of conduct, internal ethical guidelines or training initiatives aimed at promoting responsible communication. Such measures, based on autonomy and self-regulation, do not restrict legitimate political debate but can help foster an environment in which electoral competition develops in accordance with democratic values and respect for human dignity. An example is the Council of Europe’s Charter of European political parties for a non-racist and inclusive society.
