135. The next biennial renewal of the CPT’s membership is due to take place at the end of 2015, the terms of ofce of 21 members of the Committee expiring on 19 December 2015. The CPT trusts that all the national delegations concerned in the Parliamentary Assembly will put forward candidates in good time, so as to enable the Bureau of the Assembly to transmit the lists of names to the Committee of Ministers by the end of June 2015 at the latest. If the election procedure for all the seats can be completed before the end of 2015, this will greatly facilitate the planning of the CPT’s activities for the following year. 136. The spread of professional experience within the CPT’s membership remains on the whole satisfactory. However, the Committee still requires more members with frst-hand knowledge of police and prison matters and of working in forensic establishments. In this respect, it should also be kept in mind that the mandate of four psychiatrists among the current membership will expire at the end of 2015. Members with specifc experience of working with juveniles deprived of their liberty would also be an asset. Bureau of the CPT 137. During the period covered by the present report, the composition of the Committee’s Bureau remained unchanged; it consists of Lәtif Hüseynov (Azerbaijan) – President, Marzena Ksel (Poland) – 1st Vice-President and Mykola Gnatovskyy (Ukraine) – 2nd VicePresident. Elections for the Bureau of the CPT will be held at the Committee’s March 2015 plenary meeting, on the expiry of the current Bureau’s two-year term of ofce. General Report of the CPT, 2013-2014 ► Page 60 Secretariat of the CPT 138. In the course of the reporting period, the composition of the CPT’s Secretariat has undergone signifcant changes. In February 2014, the CPT’s long-serving Executive Secretary, Trevor Stevens, left the CPT’s Secretariat following his decision to retire from the Council of Europe. The CPT wishes to express its most sincere gratitude and the highest appreciation for the outstanding professionalism and personal commitment with which Mr Stevens managed the CPT’s Secretariat since its establishment 25 years ago. The new Executive Secretary, Jeroen Schokkenbroek, an experienced human rights lawyer and long-serving staf member of the Council of Europe, took up his duties in July 2014. Before his appointment, he had been, most recently, the Secretary General’s Special Advisor to Ukraine, the the Secretary General’s Special Representative for Roma issues and, prior to that, Head of the Council of Europe’s Human Rights Development Department. 139. The CPT’s Secretariat has continued to face signifcant understafng. One administrator remained on extended leave for personal reasons during the entire reference period. Further, two posts of administrators became vacant following the assignment of Thobias Bergmann (on 1 October 2013) and Johan Friestedt (on 1 September 2014) to other services of the Council of Europe. In addition, the Committee’s Deputy Executive Secretary, Fabrice Kellens, who had also acted as Executive Secretary ad interim in the frst half of 2014, was on leave during the second half of 2014. Inevitably, this challenging stafng situation has had an adverse impact on the operational
