We recommend using standard British English (e.g., centre, colour, defence, etc.); nevertheless, the most important factor should always be consistency. On occasions, texts written in British English will include references to programmes, organisations or other concepts that use a different system of spelling (American, OED, etc.). We recommend not standardising these different spellings. Thus, the words programin White House Internship Program and organization in International Maritime Organization should not be changed to programme and organisation, respectively.
