Permanent Committee on Geographical Names
"The Permanent Committee on Geographical Names (PCGN) is an inter-departmental body which was established in 1919.

Its principal function is to advise the British government on policies and procedures for the proper writing of geographical names for places and features outside the United Kingdom, excluding those of the Antarctic."

The PCGN is not subject to the Freedom of Information Act 2000 in its own right but the Ministry of Defence does answer FOI requests made to the PCGN.
