The UK government has instructed tech giants Apple and Google to block access to nude images on smartphones for under-18s. Sir Keir Starmer called for voluntary action from the companies, or legislative measures if they fail to comply within three months.

Speaking at London Tech Week, Prime Minister Rishi Sunak stated: 'These are some of the most innovative companies in the world and I believe they can solve it.' The government is set to bring forward legislation if firms do not voluntarily activate certain features that prevent children from taking, sending or viewing explicit images.

Google responded by saying it was committed to online safety but would work with UK partners on privacy-preserving solutions. Apple has not yet commented. Tech companies already have methods in place to try and prevent children from seeing or sharing nude imagery, such as age verification for apps and services like iMessage's 'Communication Safety' feature.

However, critics argue that the measures could impact user privacy, particularly by making adults verify their age. The government plans further restrictions on children’s access to social media, with a potential ban on addictive features.
