UK Prime Minister David Cameron has said that if elected again, he would push for a ban on encrypted communications services, like Snapchat, WhatsApp, and more, whose messages cannot be accessed by the country's intelligence and security agencies, even if they have a valid warrant.

The proposed reforms are part of a new legislation, which if enacted, would make it mandatory for telecom companies and Internet service providers to store more data related to people's online activities.

"Are we going to allow a means of communications which it simply isn't possible to read?" said Cameron, who has begun campaigning ahead of a national election in Britain in May. "My answer to that question is: 'No, we must not.' "

Cameron, however, didn't provide details on how he plans to enforce the new security measures, given the fact that it's extremely difficult for any government to put a complete ban on these apps, which are used by hundreds of millions of people around the world.

His comments came amid demands by many European politicians that Internet giants like Google, Facebook, Twitter, and more, allow greater government access to their user data in the wake of several recent terrorist threats, including the attacks in Paris last week, where hooded gunmen attacked the office of satirical magazine Charlie Hebdo and killed 12 people.

Similar demands have also been made back in the US, but the companies have effectively refused to give in -- Google and Apple have even started implementing encryption technologies on their respective handsets.
