The UK's Investigatory Powers (Amendment) Bill (IPB) 2024, often referred to as the "snooper's charter," has been approved by the King, making it law. The legislation enhances the digital surveillance powers of the Investigatory Powers Act 2016, allowing authorities such as intelligence services and the police to access more data. Government and security officials argue these enhancements are necessary to address contemporary threats including terrorism and child exploitation. The amendments include new provisions for gathering internet connection records and bulk datasets from publicly accessible sources like social media. Critics, including tech companies and privacy advocates, argue that the bill severely compromises privacy, lacks adequate safeguards, and was expedited through the legislative process without thorough scrutiny. Key concerns also include the potential undermining of security measures in tech products, as the bill requires companies to consult with the government prior to deploying security updates. Privacy International and other rights groups continue to express disappointment, stating that the bill worsens already insufficient privacy protections and broadens surveillance capabilities significantly. The future steps for the bill include consultations on its implementation, where stakeholders hope to influence a more balanced approach to its regulations.
