- 26 It is hoped that by 1993 the Committee will have attained its objective of a rhythm of visits ensuring that each Party is visited on a periodic basis every two years, in addition to any ad hoc or follow-up visits that might prove necessary. In the CPT's view, anything longer than a two-year interval being periodic visits to a given country would seriously undermine the Committee's credibility. 90. The envisaged increase in the number of the CPT's visits over the coming years will inevitably be dependent on the Committee being provided with adequate Secretariat resources. At present, the CPT's Secretariat has five officials, comprising two A grade staff and three support staff. The Secretariat should soon be reinforced by two further A grade officials and another secretary. However, it is clear that in due course additional staff will have to be made available if the above-mentioned objective is to be attained. In this connection, it should be underlined that the Secretariat has an essential role to play in the preparation and carrying out of visits and in the subsequent drawing up of visit reports. d) Increasing knowledge of the CPT's activities 91. As early as November 1989, the CPT requested the States Parties to inform, by appropriate means (instructions, circular letters, etc) the relevant national authorities and staff (prison governors, prison officers, police officers, etc) of the existence, powers and role of the Committee. It also called upon the States Parties to include information on the Convention in the training of law enforcement personnel and other staff working with persons deprived of their liberty. The Committee took this step because it thought that the more national authorities and staff responsible for places of detention knew about the Committee's role, the greater would be their co-operation with the Committee when it visited their country. In addition, knowledge about the CPT's existence and activities might constitute an incentive to ensuring that the rights of persons deprived of their liberty are fully respected. 92. To the best of the Committee's knowledge, far from all the Parties have heeded these requests. This is a matter of regret and concern for the CPT, as a wider dissemination of information about its role would greatly facilitate the accomplishment of its tasks. The CPT therefore intends to renew its requests. 93. The CPT believes that any circulars, instructions or documents concerning its role and activities should also be disseminated in places of detention, so as to bring the existence of the CPT to the attention of those most concerned by its work. 94. The CPT would also like to suggest to the relevant Council of Europe bodies that they consider the idea of organising in the future one or more training sessions for the various categories of national officials involved in the application of the Convention (prison governors, police officers, etc). The purpose of these sessions would be to sensitise the aforementioned officials to the Convention and the action of the CPT.
