However, it was never extended to cover members of the new devolved legislatures.

The use of electronic surveillance by the United Kingdom grew from the development of signal intelligence and pioneering code breaking during World War II. In the post-war period, the Government Communications Headquarters (GCHQ) was formed and participated in programmes such as the Five Eyes collaboration of English-speaking nations. This focused on intercepting electronic communications, with substantial increases in surveillance capabilities over time. A series of media reports in 2013 revealed bulk collection and surveillance capabilities, including collection and sharing collaborations between GCHQ and the United States' National Security Agency. These were commonly described by the media and civil liberties groups as mass surveillance. Similar capabilities exist in other countries, including western European countries.
During the 2010s, international media news reports revealed new operational details about the Anglophone cryptographic agencies' global surveillance of both foreign and domestic nationals. The reports mostly relate to top secret documents leaked by ex-NSA contractor Edward Snowden. The documents consist of intelligence files relating to the U.S. and other Five Eyes countries. In June 2013, the first of Snowden's documents were published, with further selected documents released to various news outlets through the year.
The global surveillance disclosure released to media by Edward Snowden has caused tension in the bilateral relations of the United States with several of its allies and economic partners as well as in its relationship with the European Union. In August 2013, U.S. President Barack Obama announced the creation of "a review group on intelligence and communications technologies" that would brief and later report to him. In December, the task force issued 46 recommendations that, if adopted, would subject the National Security Agency (NSA) to additional scrutiny by the courts, Congress, and the president, and would strip the NSA of the authority to infiltrate American computer systems using "backdoors" in hardware or software. Geoffrey R. Stone, a White House panel member, said there was no evidence that the bulk collection of phone data had stopped any terror attacks.
Global mass surveillance can be defined as the mass surveillance of entire populations across national borders.
