Is spying necessary?
Ten Russian spies caught living in the US have been deported to Russia, following the biggest 'spy swap' since the end of the Cold War. Does spying still have a purpose in the world today?
The ten Russian agents left New York after a judge ordered their expulsion during a court hearing at which they admitted spying for a foreign country.
Meanwhile, Russian President Dmitry Medvedev has pardoned four people convicted of espionage in Russia.
Two of the four Russians expelled from Moscow are reported to be staying undercover in a British hotel.
How essential are intelligence services for countries? Are there better ways of getting information? What impact does it have with relations between nations?
