# Official Secrets Act 1911

The Official Secrets Act 1911 (1 & 2 Geo. 5. c. 28) was an Act of the Parliament of the United Kingdom. It replaced the Official Secrets Act 1889.
The Act was introduced in response to public alarm at reports of wide-scale espionage, some of them fomented by popular novels and plays that dramatized the threat, supposedly from Germany, at a time of a rapid naval expansion. Its provisions were extensive, with heavy penalties for any reporting or sketching of military, naval or air defence installations, or the harbouring of people suspected of gathering such intelligence.
It was amended several times; most importantly the "catch-all" provisions contained in section 2 of the Act were repealed and replaced by the Official Secrets Act 1989. The Act applied in the United Kingdom, the Isle of Man, the Channel Islands, and in overseas crown territories and colonies. It also applied to British subjects anywhere else in the world.
The Act was repealed and replaced in 2023 by the National Security Act 2023.
In the Republic of Ireland, the Act was repealed by section 3 of the Official Secrets Act 1963.

## Background

The Act was passed during a febrile period of "spy fever" in the years leading up to the First World War, with widespread anti-German sentiment in Britain provoked by the Anglo-German naval arms race and events such as the Kruger telegram and the Agadir Crisis. These fuelled numerous press and literary accounts of imaginary German undercover activities, such as William Le Queux's 1909 book, Spies for the Kaiser. Plotting the downfall of England. By the end of 1908, newspapers were receiving hundreds of fanciful letters detailing the activities of suspected German spies. For example, a letter in the Morning Post in May 1907 claimed that there were 90,000 German reservists and spies in Britain, with weapons caches for them in every major city, whilst an article in the 1909 edition of The Annual Register alleged that 50,000 Mauser rifles stored in a cellar near Charing Cross were intended for the 66,000 German reservists rumoured to be in London. Invasion fiction also became extremely popular, with novels such as Erskine Childers' 1903 The Riddle of the Sands, Le Queux's The Invasion of 1910 serialised by the Daily Mail in 1906, and Saki's When William Came of 1913.
The 1911 Agadir Crisis, in which the UK threatened war with Germany, was the final trigger for the government. In an atmosphere of widespread hysteria, it introduced the act in the House of Lords on 25 July 1911. The act was then rushed through Parliament, with little debate or opposition, passing through all of its stages in a single day, 18 August 1911, and receiving royal assent four days later on 22 August. The act, with its extremely wide-ranging powers, replaced the earlier Official Secrets Act 1889 that had provided criminal sanctions only for breaches which could be shown to be contrary to the public interest. Section 1 of the act contained tough provisions against espionage, which were extended by a 1962 Law Lords ruling to cover other activities such as sabotage and physical interference. Section 2 dealt with unauthorised disclosure of information held by servants of the State, making it a criminal offence to disclose any official information without lawful authority. It was only after nearly 80 years that the Official Secrets Act 1989 replaced this provision in the 1911 Act.

## Section 1 - Penalties for spying

This section is very broadly drafted.

### Section 1(1)

This subsection reads as amended:
   1. — (1) If any person for any purpose prejudicial to the safety or interests of the State—

       (c) obtains, [collects, records, or publishes,] or communicates to any other person [any secret official code word, or pass word, or any sketch, plan, model, article, or note, or other document or information which is calculated to be or might be or is intended to be directly or indirectly useful to an enemy;
   he shall be guilty of felony ...

   On a prosecution under this section, it shall not be necessary to show that the accused person was guilty of any particular act tending to show a purpose prejudicial to the safety or interests of the State, and, notwithstanding that no such act is proved against him, he may be convicted if, from the circumstances of the case, or his conduct, or his known character as proved, it appears that his purpose was a purpose prejudicial to the safety or interests of the State; and if any sketch, plan, model, article, note, document, or information relating to or used in any prohibited place within the meaning of this Act, or anything in such a place [or any secret official code word or pass word], is made, obtained, [collected, recorded, published], or communicated by any person other than a person acting under lawful authority, it shall be deemed to have been made, obtained, [collected, recorded, published] or communicated for a purpose prejudicial to the safety or interests of the State unless the contrary is proved.
The words in square brackets were inserted by the Official Secrets Act 1920.
