Dr Jade Leung named AI Security Institute Vice-Chair

According to the government announcement, Dr Jade Leung is moving into two new roles: Vice-Chair of the AI Security Institute and Security Advisor to the AI Taskforce. At the same time, she will step back at the end of September from her full-time posts as the Prime Minister’s Adviser on AI and Chief Technology Officer of the institute, with the change linked to personal circumstances. If you have not been following every change inside government, here is the simple version. This is not a full departure. It is a reshaping of one of the most important AI policy jobs in government, with Leung still staying close to the work.

The government release says Leung has helped shape the UK’s approach to advanced AI across the public sector, national security and economic growth. It also says she played a leading role in setting up the AI Security Institute, helping build its technical research capability and its programme of work. That matters because AI policy is not only about new tools appearing in schools, offices or on your phone. It is also about who tests powerful systems, who spots risks early, and who advises ministers before decisions are made. When someone with that kind of reach changes role, it is worth paying attention.

The AI Security Institute can sound distant or overly technical, so it helps to translate it into everyday language. You can think of it as the part of government focused on the safety and security side of advanced AI: what these systems can do, where they could go wrong, and what evidence ministers need before moving quickly. Leung becoming Vice-Chair means she is still tied to that mission. **What this means:** even though she is leaving the full-time chief technology officer post, she is not being moved away from the central questions about AI safety. She is still being kept near the decisions that shape the institute’s direction.

Her second new title matters just as much. The government says Leung will serve as Security Advisor to the AI Taskforce, continuing to give strategic advice on AI safety and security while the UK prepares for both the opportunities and the challenges of advanced AI. The announcement does not spell out every detail of the taskforce’s day-to-day work, but the title tells us something important. A security adviser is there to make sure risk is not treated as an afterthought. **Why this matters:** when governments talk about growth and innovation, there is always a danger that safety gets pushed to the side. This appointment suggests ministers want security concerns kept inside the main conversation.

Leadership changes like this can look minor on paper, but they often tell you a lot about what a government is trying to protect. In AI, continuity matters because the field moves quickly and the stakes are high. A change in personnel can shift priorities, slow decisions, or change how bluntly risks are described behind closed doors. That is why this story is about more than one person’s new job title. It is also about whether the UK wants steady hands on AI safety while it keeps pushing for economic growth and technical progress. **What to watch:** not just who holds office, but what kind of judgement they bring to it.

There is another detail in the government statement that helps explain the bigger picture. Alongside her new UK roles, Leung will take up a part-time position as a Distinguished Visiting Fellow at Stanford University’s Hoover Institution. That points to a career that will now sit partly inside government and partly alongside academic and policy debate. At the same time, the government says a new Adviser on AI to the Prime Minister will be appointed in due course. That replacement will matter. The next adviser will inherit a role that touches public services, national security and growth, which means this is not simply an internal staffing update. It is a signpost for where Downing Street may go next on AI.

In the same government release, Prime Minister Andy Burnham said Britain is better prepared for the opportunities and challenges of AI because of Leung’s work, and that he was pleased she would continue in government. AI Minister Kanishka Narayan also praised her, saying she helped build the institute, secure an AI agreement between the UK and Ukraine, and establish AI Growth Zones across the UK. For readers, the useful lesson is this: official announcements are not only about praise. They are also clues. **What it means for you:** the UK appears to want stability on AI safety even while senior roles are changing. The next big question is who becomes the Prime Minister’s new AI adviser, and whether that person keeps safety and security at the centre of the government’s AI plans.
