Official Secrets Act

An Official Secrets Act (OSA) is legislation that provides for the protection of state secrets and official information, mainly related to national security but in unrevised form (based on the UK Official Secrets Act 1911) can include all information held by government bodies.

OSAs are currently in-force in over 40 countries (mostly former British colonies) including Bangladesh, Kenya, Pakistan, Hong Kong, India, Ireland, Myanmar, Uganda, Malaysia, Singapore and the United Kingdom, and have previously existed in Canada and New Zealand.

There were earlier English and British precedents, long before the acts enumerated here. As early as the 16th Century, following Francis Drake's circumnavigation, Queen Elizabeth I declared that all written accounts of Drake's voyages were to become the "Queen's secrets of the Realm".^{[citation needed]} In addition, Drake and the other participants of his voyages were sworn to their secrecy on the pain of death; the Queen intended to keep Drake's activities away from the eyes of rival Spain.
