Organisations, government and departments
Organisations are singular. The government is (not are) or the BGS is (not BGS are).
Use an initial capital for all governments, British and overseas, when referring to a specific one, e.g. ‘the Government issued a press release’.
Use lowercase government in all adjectival contexts, e.g. a government minister, a government decision, government expenditure.
Government departments should be in capitals e.g. Department for Business, Enterprise & Regulatory Reform.
