The UK government has intensified pressure on major technology firms, warning that stronger laws could be introduced unless companies take immediate action to improve online protections for children.

Speaking during a major technology policy event in London, Prime Minister Sir Keir Starmer announced that smartphone and platform providers have been given a limited timeframe to deploy tools capable of preventing children from sending, receiving, or viewing explicit images. The move forms part of a broader push to strengthen online safety and child protection measures across the UK.

The proposals would require technology companies to activate or develop systems capable of identifying and blocking inappropriate content on devices used by minors. Government officials argue that advances in technology make such safeguards technically achievable and necessary to combat online exploitation and harmful digital content.

Ministers have indicated that failure to act voluntarily could result in new legislation compelling firms to introduce the required protections. The government says its objective is to reduce online risks facing young people while maintaining access for adults through age-verification measures.

The announcement comes amid growing concern over children's online wellbeing, digital safety, and the role of major technology companies in protecting younger users. Child safety advocates have welcomed stronger action, while industry observers are closely watching how leading technology firms respond to the government's demands.

The proposal is expected to remain a major political and technology policy issue throughout the summer as discussions continue between government officials, regulators, and technology companies.
