SHealth secretaries have informed the social media giants to purge their places of personal injury and suicide material or face the law.
Matt Hancock, Secretary of State for Health and Social Services, wrote this weekend to the heads of social networks that warn that the action is "urgently" necessary to ensure that they do not violate the policies of the Internet providers.
In the letter, Mr. Hancock expresses its growing concern about the harmful content online, and claims that it is "scary" how easy it is to access content that "leads to harming oneself and promoting suicide."
The letter, sent to business leaders on Facebook, Instagram, Twitter, Snapchat, Pinterest, Google and Apple, is just a few days after Father Ian Russell talked about how Instagram "helped" kill his 14-year-old daughter , Molly.
In the year 2017, Molly was found dead in the chamber after showing "without obvious signs" of mental health problems, but her family later found that she had been observing material on social media linked to the # 39 Anxiety, depression, self-injury and suicide.
Hancock wrote in his letter: "Like any parent, I was horrified to learn from Molly Russell, 14, who tragically took his own life.
"The pain Molly's parents feel is that no-one should have to experience. All suicide is a preventable death, including Molly's."
He continued: "It is terrible how easy it continues to have to access this content online and I have no doubt about the damage that this material can cause, especially for young people.
"It is high time that Internet and social media providers intensify and purge this content once and for all.
"I want to work with providers of Internet and social media to ensure that the action is as effective as possible.
"However, let's make sure that we will introduce new legislation when necessary."
Hancock ends with his essay: "I hope to work with you with the urgency that this agenda needs."
