A Royal Rethink: Lawyers Debate the Legal Path to a UK Republic
Written by Kate Washington - 16 March 2026
If recent developments involving Andrew Mountbatten-Windsor (formerly Prince Andrew, Duke of York) show anything, it is that even members of the royal family are subject to the rule of law. Debates about the future of the British monarchy tend to arise whenever a royal controversy is in the headlines, but the latest news surrounding Andrew Mountbatten-Windsor has prompted a slightly different conversation: not just whether the monarchy is popular, but whether the UK could legally dismantle it altogether. Could the UK legally replace the monarchy with a republic?
At first glance, dismantling an institution that has existed for centuries might sound legally impossible, but some constitutional lawyers say the pathway is surprisingly clear. The reason lies in a core principle of the UK’s constitutional system: parliamentary sovereignty. As the UK does not have a single written constitution, Parliament has the authority to change constitutional arrangements through legislation.
According to Geoffrey Robertson KC, this means that MPs could amend laws such as the Act of Settlement 1701, which governs who can become monarch. If lawmakers chose to do so, they could replace the hereditary monarch with an elected head of state, potentially serving a fixed term.
However, not everyone in the legal world thinks it would be so simple. Robert Buckland KC, a former Conservative justice secretary, argues that abolishing the monarchy would require “obvious and fundamental changes” to UK law, especially considering that the monarch’s role appears throughout British law and government. For example, legislation receives royal assent, passports are issued in the monarch’s name, and certain executive powers are formally exercised under the royal prerogative. Removing the monarchy would therefore require revisiting large areas of legislation and constitutional practice.
For aspiring lawyers, this is more than just a thought experiment; the debate highlights how political and constitutional questions like this can influence the market and create significant work for the legal profession. Any serious attempt to redesign the UK’s constitutional structure would likely involve teams of public law specialists advising government, parliamentary committees and campaign groups. Law firms could also find themselves handling disputes over assets, institutional powers or transitional arrangements.
In practice, that means that law firms would likely play a central role in shaping how such a constitutional shift would unfold legally. In other words, while the question of whether the UK should become a republic is ultimately political, figuring out how it could happen would be a major legal exercise.
For law students watching from the sidelines, this is a reminder that even centuries-old institutions operate within legal frameworks, and when those frameworks change, lawyers are often close to the action.
