9 e. Future developments - increasing the number of CPT members with relevant professional experience 26. The CPT must emphasise once again the importance of increasing the number of its members who possess specialist practical knowledge of penitentiary systems or are medical doctors with relevant experience (see also the 1st General Report, op. cit. paragraphs 87 and 88). In this regard, the Committee wishes to refer to and strongly endorse certain of the observations on Article 4 (2) of the Convention made in paragraph 36 of the Explanatory Report: "It would be desirable that the Committee should include members who have experience in matters such as prison administration and the various medical fields relevant to the treatment of persons deprived of their liberty. This will make the dialogue between the Committee and the States more effective and facilitate concrete suggestions from the Committee". 27. Unless more members are elected with professional experience in the above-mentioned areas, there is a risk that the influence of assisting "experts" (cf. Article 7 (2) of the Convention) over the CPT's activities will become greater than that envisaged by the authors of the Convention. - increasing the number of visits 28. In 1992 the CPT plans to carry out periodic visits to eight Parties to the Convention - Cyprus, Finland, Italy, Luxembourg, the Netherlands, Portugal, San Marino and Turkey (the visits to Italy and San Marino to take place concurrently), to which must be added any ad hoc visits that might appear to the Committee to be required. Looking further ahead, the CPT hopes to organise nine periodic visits in 1993 i.e. to approximately one third of the States Parties to the Convention (which can be expected to number 25 or more by that time). 29. The CPT's objective remains a rhythm of visits ensuring that each Party is visited on a periodic basis every two years, though the gap between visits might be somewhat longer in the case of countries with very small populations. In this connection, it should be recalled that in most Parties to the Convention there are many places of various types falling within the CPT's mandate, and that in the course of a given visit the Committee is only in a position to go to a very limited number of those places. - increasing knowledge of the CPT's activities 30. In its 1st General Report (op. cit. paragraphs 91 to 94), the CPT stressed the importance of increasing knowledge of the CPT's activities. The Committee is most grateful to the Committee of Ministers for having endorsed, in June 1991, its requests to States Parties to inform by appropriate means the relevant national authorities and staff of the existence, powers and role of the Committee, and to include information on the Convention in the training of law enforcement personnel and other staff working with persons deprived of their liberty.
