Former US intelligence contractor Edward Snowden revealed on Monday the UK government acquired vast amounts of communications data from inside Pakistan by secretly hacking into routers manufactured by the US company, Cisco.
In an interview with BBC's Panorama programme, the whistleblower said British spies can hack into phones remotely with a simple text message and make audio recordings or take photos without owners knowing.
"They want to own your phone instead of you," Snowden said, referring to Britain's Government Communications Headquarters (GCHQ) agency.

Snowden claimed that GCHQ used a series of interception tools called "Smurf Suite", after the blue cartoon characters, The Smurfs.
"Nosey Smurf" enabled spies to switch on a smartphone's microphone even if the phone was off, he claimed.
Other programmes used by GCHQ were nicknamed "Tracker Smurf" and "Dreamy Smurf", which allows phones to be switched on and off remotely, Snowden said.
He said the text message sent by GCHQ to gain access to the phone would not be noticed by its owner.
"It's called an 'exploit'," he said.
"When it arrives at your phone it's hidden from you. It doesn't display. You paid for it but whoever controls the software owns the phone," he added.

The BBC said the government had declined to comment in line with usual policy on intelligence matters.
Snowden, who has been charged by the US with espionage and theft of government property after leaking documents to the media about digital espionage, has been living in exile in Russia since June 2013.
The British government is planning legislation that would give more powers to intelligence agencies to monitor online activity to investigate crime.
