Denmark was involved in US plans to extradite former intelligence contractor Edward Snowden to the United States in 2013, Danish Justice Minister Soren Pind said Friday.
A US government plane had in the summer of 2013 been given permission to land at Copenhagen airport and fly over Danish airspace in preparation for the possibility that Snowden could be delivered from Russia or another country.
In a letter from Pind to the parliament's legal affairs committee, Pind outlined Denmark's participation in the US extradition plan, Danish news agency Ritzau reported Friday.
Josephine Fock, a member of the legal affairs committee and the opposition party Unity List, said her party would continue to seek information about Denmark's role, public broadcaster DR reported.
US authorities have been seeking Snowden on espionage charges following his 2013 disclosure of extensive telephone and internet data-collection programmes used by the US National Security Agency (NSA).
He was in Hong Kong at the time the US charges were leveled, after which he fled on an Aeroflot flight to Moscow despite the fact that the US had revoked his passport.
During 2013, Denmark, a NATO member, was led by a left-leaning coalition under former Social Democrat leader Helle Thorning Schmidt.
The US reportedly contacted several Scandinavian nations to help in the extradition of the whistle-blower, according to documents revealed by Norway's national broadcaster NRK in 2015.
On Twitter, Snowden, who currently has asylum in Russia, said it appeared that "Denmark intended to violate principle of non-refoulement as I sought asylum," citing the online edition of Danish daily Information.
