Interception
What interception means
Interception means the interception of communication in the course of its transmission via a postal service or telecommunications system such as telephone or email, so as to make it available to a third party.
The law permits interception of communications by law enforcement and intelligence agencies in tightly controlled circumstances in the interests of national security, preventing or detecting serious crime or safeguarding the economic well-being of the UK. Read the Interception code of practice
