MI5's Andrew Parker briefed the PM about a reluctance among internet firms to cooperate with tracking terrorists David Cameron has been warned by the country’s top spy chiefs that internet companies including Facebook and Google are undermining national security. The Prime Minister was told internet giants have ‘withdrawn’ their cooperation and are obstructing MI5 requests for help tracking terrorists and major criminals, including paedophiles. It follows fugitive Edward Snowden’s claims that the firms are used to snoop on British citizens, which is disputed by spy chiefs. Before the US whistleblower’s disclosures, they willingly responded to lawful requests for details of phone calls, emails, text messages and other private information.
