Appointments to the BRC are made by the Chancellor, subject to the consent of the Treasury Select Committee. When appointing executive members of the BRC, the Chancellor will consult with the Chair of the OBR. For appointments of non-executive members, the recruitment process will be conducted by the OBR, but the final appointment will be made by the Chancellor. The interview panel for this is chaired by a non-executive member of the OBR and includes a lead Treasury official. Further information on appointments can be found in the OBR and HM Treasury framework document available here: www.gov.uk/government/uploads/system/uploads/attachment_data/file/314705/PU1675_OBR_and_HMT_framework_document.pdf
During the last recruitment exercise for a board member of the OBR, where the Chancellor appointed the executive BRC member Sir Charlie Bean, 6 applications were received.
Table 2.3 in the OBR’s 2015-16 annual report and accounts specifies that one female and 4 males make up the BRC and non-executive members. The report is available here: www.budgetresponsibility.org.uk/docs/dlm_uploads/56061-OBR-AR-2016_Web.pdf). A breakdown of the board by ethnicity, disability and socio-economic background is not publically available.
