The complainant submitted a request to the Foreign, Commonwealth & Development Office (FCDO) seeking information about the then Duke of York’s visit to Azerbaijan in 2009. The FCDO disclosed some information in response to the request but withheld further information on the basis of sections 27(1)(a) and (d) (international relations), 40(2) (personal data) and 43(2) (commercial interests) of FOIA. The Commissioner’s decision is that the information withheld under sections 27(1)(a) and (d) is exempt from disclosure on the basis of those exemptions. However, he has concluded that the information that has only been withheld on the basis of section 43(2) is not exempt on the basis of that exemption.
