Paragraph 61: Recommendation to the Greek authorities to take the necessary steps to ensure that, at Petrou Ralli and Thessaloniki holding facilities:  medical screening is systematically carried out upon admission;  a doctor and at least one nurse are present every day, including on weekends; visiting specialists, including psychiatrists and dentists regularly attend;  a system is established (e.g. written requests to be directly collected by health care personnel) to allow detainees to directly request consultations with health-care staff;  medical confidentiality is strictly guaranteed;  self-harm and suicide preventive measures are put in place. Relevant points are made in paragraphs 57 (on the Directorate of Foreign Nationals of Thessaloniki) and 58 (on the Directorate of Foreign Nationals of Attica). Paragraph 61: Request for information: procedures in place to expedite the return of persons who volunteer to return to their country of origin, especially when they are willing to purchase their own air tickets At the moment, to meet the unquestionable obligation stemming from European decisions on effective returns, despite the delays observed because of non-absorption to date of the funding approved for our country owing to long-lasting tender procedures (regular AMIF Programme), the Hellenic Police has reached an agreement with FRONTEX-European Border and Coastguard Agency which, in collaboration with the other Member States, makes aircrafts available both for organizing return operations from our country and for our participation therein (flights passing through Greece to receive migrants to be returned to their country of origin) at no cost for our budget. It is noted that this agreement has been expanded, since FRONTEX-European Border and Coastguard Agency has notified us on the possibility to ensure aircrafts for Greece to conduct domestic return flights in case of increased numbers of irregular migrants to be returned. Moreover, foreign nationals are regularly informed by competent police agencies that, if they wish to depart voluntarily for their country of origin or any other third country of their choice (which will lawfully admit them on its territory), apart from the possibility of joining assisted voluntary return (AVR) programmes of the International Migration Organisation (IOM), they can pay themselves for their return ticket, thereby expediting the relevant procedure.
