United Kingdom

Combating terrorism and preventing child abuse have been widely used by state agencies and private commercial actors to justify the implementation of interception of communications and direct filtering measures in the country.

In December 2008, a number of British internet service providers blocked a Wikipedia page displaying an image of an album cover from 1976 that portrayed a naked teenage girl.

Law requires that information that glorifies or incites terrorism be censored. Filtering technologies such as the "CleanFeed" system are criticized for not publicizing the list of filtered websites, which could lead to abuses.
