International regulators are finalizing the first global safety standards for Automated Driving Systems (“ADS”). In January, the UN Working Party on Automated/Autonomous and Connected Vehicles (“GRVA”) approved a draft UN Regulation (“UNR”) under the 1958 Agreement and a draft Global Technical Regulation (“GTR”) under the 1998 Agreement, submitting both for adoption by the UN World Forum for Harmonization of Vehicle Regulations.

Developed in parallel to ensure harmonized technical requirements across jurisdictions, the UNR and GTR are expected to be adopted at the 199th WP.29 session in June 2026. In the meantime, work continues on finalizing the accompanying Guidance and Interpretation Document. This post provides an overview of the UN regulatory framework, the legislative status of the ADS instruments as of May 2026, an outline of the key provisions, and implications for companies across the ADS value chain.

Artificial intelligence (“AI”) continues to reshape the UK financial services landscape in 2026, with consumers increasingly relying on AI-driven tools for financial guidance and firms deploying more autonomous systems across their businesses.

The Financial Conduct Authority (“FCA”), Prudential Regulation Authority (“PRA”) and Bank of England (“BoE”) (together “the Regulators”) have consistently signalled that AI will be overseen through existing regulatory frameworks, rather than through bespoke AI-specific rules. At the same time, political scrutiny is intensifying, supervisory expectations are rising, and the Regulators are investing heavily in sandbox initiatives and long-term reviews to test whether those frameworks remain fit for purpose.

This article explores the latest policy signals, supervisory initiatives and regulatory tools shaping the UK’s evolving approach to AI in financial services.

On March 25, 2026, the UK’s Office of Communications (“Ofcom”) and the Information Commissioner’s Office (“ICO”) published a joint statement setting out their common expectations for age assurance on online services (“Joint Statement”). The Joint Statement is aimed at services likely to be accessed by children that fall within the scope of the Online Safety Act 2023 (“OSA”) and UK data protection legislation, and is designed to help providers comply with both their online safety and data protection obligations when deploying age assurance.

The Joint Statement arrives alongside a broader push from both regulators—including Ofcom’s recent call to action directed at major tech firms, an open letter from the ICO urging platforms to strengthen their age checks, and several enforcement actions by both regulators.

On March 2, 2026, the UK Department for Science, Innovation and Technology (“DSIT”) launched its consultation, titled “Growing up in the online world: a national conversation”. The consultation is open until 26 May 2026, after which the government will publish a summary of responses and its proposed approach. DSIT has indicated that it intends to move quickly on the consultation’s findings, drawing on newly granted powers that allow for accelerated implementation of online safety measures.

The consultation seeks views on a wide range of potential measures to strengthen children’s safety and wellbeing online, including more robust age‑assurance mechanisms, a statutory minimum age for social media, raising the UK’s age of digital consent, restrictions on certain features (such as livestreaming and disappearing messages), and new obligations for AI chatbots and generative‑AI services.

DSIT’s proposals could significantly expand regulatory expectations beyond the Online Safety Act 2023 (“OSA”)—including potential age‑based access limits (including differing safeguards as between teens and younger children), feature‑level restrictions, and enhanced duties for AI‑enabled services. Early engagement will be important to ensure that the government takes account of the views of affected service providers and understands the operational and technical implications of the measures proposed.

On 8 October 2025, the European Commission published its Apply AI Strategy (the “Strategy”), a comprehensive policy framework aimed at accelerating the adoption and integration of artificial intelligence (“AI”) across strategic industrial sectors and the public sector in the EU.

The Strategy is structured around three pillars: (1) introducing sectoral flagships to boost AI use in key industrial sectors; (2) addressing cross-cutting challenges; and (3) establishing a single governance mechanism to provide sectoral stakeholders a way to participate in AI policymaking.

The Apply AI Strategy is accompanied by the AI in Science Strategy, and it will be complemented by the Data Union Strategy (which is anticipated later this year).

On June 26, 2025, the European Parliament’s Committee on Employment and Social Affairs published a draft report (“Draft Report”) recommending that the Commission initiate the legislative process for an EU Directive on algorithmic management in the workplace.  The Draft Report defines algorithmic management as the use of automated systems—including those involving artificial intelligence—to monitor, assess, or make decisions affecting workers and solo self-employed persons.

This Draft Report follows a Commission study published in March 2025 (“Commission Study”), which found that while existing EU legislation, such as the GDPR, addresses some risks to workers from algorithmic management, others remain.  The Commission Study also recognizes that the AI Act does not establish specific rights for workers in the context of AI use, which is noted as a concern.

The Draft Report encloses the proposed text for a new Directive on algorithmic management in the workplace (“Proposed Directive”).  The Draft Report has not yet been endorsed by the European Parliament.

On June 3, 2025, the OECD introduced a new framework called AI Capability Indicators that compares AI capabilities to human abilities. The framework is intended to help policymakers assess the progress of AI systems and enable informed policy responses to new AI advancements. The indicators are designed to help non-technical policymakers understand the degree of advancement of different AI capabilities. AI researchers, policymakers, and other stakeholder groups, including economists, psychologists, and education specialists, are invited to submit their feedback to the current beta-framework.

In February 2025, the European Commission published two sets of guidelines to clarify key aspects of the EU Artificial Intelligence Act (“AI Act”): Guidelines on the definition of an AI system and Guidelines on prohibited AI practices. These guidelines are intended to provide guidance on the set of AI Act obligations that started to apply on February 2, 2025 – which includes the definitions section of the AI Act, obligations relating to AI literacy, and prohibitions on certain AI practices.

This article summarizes the key takeaways from the Commission’s guidelines on the definition of AI systems (the “Guidelines”). Please see our blogs on the guidelines on prohibited AI practices here, and our blog on AI literacy requirements under the AI Act here.

On April 3, 2025, the Budapest District Court made a request for a preliminary ruling to the Court of Justice of the European Union (“CJEU”) relating to the application of EU copyright rules to outputs generated by large language model (LLM)-based chatbots, specifically Google’s Gemini (formerly Bard), in response to a user prompt. This Case C-250/25 involves a dispute between Like Company, a Hungarian news publisher, and Google Ireland Ltd.
