Prime Minister David Cameron vowed in 2013 to block pornographic material from “the darkest corners of the internet.”
Cameron announced in July that most households in the UK would have pornography blocked by their internet provider unless they chose to receive it.
Online pornography was “corroding childhood” and “distorting” children’s understanding of sex and relationships, he argued.
The UK’s biggest internet service providers have agreed to the filters scheme meaning it should cover 95% of homes.
