Edward Snowden has been pictured in public today for the first time since leaving Moscow airport.

The National Security Agency whisteblower emerged to collect the Sam Adams Associates Integrity in Intelligence Award.

The picture was published on the same day his father Lon Snowden arrived in Russia to see his son.

Dressed in a black suit and open-necked blue shirt, Snowden was seen smiling alongside UK WikiLeaks journalist Sarah Harrison, who took the leaker from Hong Kong to Moscow and also obtained his asylum.

The precise location of the award ceremony is not known, although it is believed to have been in Moscow.

The award is given annually for people operating within the intelligence community who stand up to abuse of information gathering.

Previous winners include Wikileaks founder Julian Assange and former British Intelligence translator Katharine Gun who leaked information suggesting America acted illegally in pushing for the 2003 invasion of Iraq.
