Facebook users will be given a new legal right to wipe clean all photos, messages and information that they put online before turning 18 under a new manifesto pledge announced by Theresa May.
The Prime Minister will announce plans for new legislation to amid concerns that people’s career prospects are being damaged by comments they made as teenagers.
Social media companies will also face significant fines if they fail to stop people from “unintentionally” coming across pornography, hate speeches and other harmful material.
They will also be legally obliged to take down “inappropriate, bullying, harmful or illegal content” that is flagged to them by users or fines.
The Tories will also unveil new powers to hit the entire social media industry with a multi-million pound fines if it fails to fulfill its responsibilities to protect users.
It comes after criticism of Facebook, Youtube and other social media websites for hosting videos of hate clerics and even child abuse online.
The policy represents a significant shift for the Conservatives, who have previously worked with companies in the hope that they will voluntarily make the changes.
Mrs May said: “The internet has brought a wealth of opportunity but also significant new risks which have evolved faster than society’s response to them.
“We want social media companies to do more to help redress the balance and will take action to make sure they do. “These measures will help make Britain the best place in the world to start and run a digital business, and the safest place in the world for people to be online.”
