The Security Services have countered terrorist threats to UK interests, both at home and overseas, since the 1960s and the threat has developed significantly since then.
Terrorism threats to the UK cover International terrorism, Northern Ireland-related terrorism (NIRT), Right Wing terrorism (RWT) and Left, Anarchist and Single-Issue terrorism (LASIT).
The threat of espionage (spying) did not end with the collapse of Soviet communism in the early 1990s. Espionage against UK interests still continues and is potentially very damaging.
The proliferation of weapons of mass destruction (WMD) poses a potential threat to the UK's security. A number of countries continue to develop WMD programmes which give cause for concern.
