Home Secretary Sajid Javid has insisted that the government will "not be afraid to take action" against tech firms if they do not help their efforts, saying they either need to take more measures or they will instead face new legislation.
He explained: "I've been impressed by the progress the likes of Google, Facebook, Microsoft, Twitter and Apple have made on counter-terrorism.
"Now I want to see the same level of commitment from these companies and others for child sexual exploitation."
He said, too, that some well-known sites have not taken the issues seriously enough for his liking.
Javid admitted that the current landscape has quickly developed, adding that the technology industry in the UK has not been able to keep pace with the problem.
He said: "The threat has evolved a lot more quickly than the industry's response and industry has just not kept up.
"So let me say this - I'm not just asking for change, I am demanding it and the people are demanding it too - and if the web giants do not take more measures to remove this type of content from their platforms, I will not be afraid to take action."
