Edward Snowden 'carried out public service, but should still face trial'

Former US attorney general Eric Holder has said whistleblower Edward Snowden performed a "public service" by sparking a debate about secret domestic surveillance programmes, but insisted that he should still return to the US to stand trial.

As a National Security Agency contractor, Mr Snowden leaked details in 2013 of the US government's warrantless surveillance of its citizens before fleeing the country.
