Thomas leads on maximising opportunities for collaboration with other research-focused organisations in the constitutional sphere, and supports effective two-way engagement with relevant policymakers and commentators. 

He has a professional background in Westminster politics, where he worked closely with a wide range of MPs and peers – most notably serving for five years as a senior aide and political adviser to the Rt Hon Sir Oliver Letwin, including through the political and constitutional upheavals of the 2017–19 parliament.  

Thomas also spent two years as Deputy Director of the ‘Red Tape Initiative’, a government-backed project to identify EU-derived regulation that could be improved upon following Brexit, via cross-party consensus.  

Outside of his work with the Constitution Unit, Thomas is also the Advocacy and Engagement Director of the ‘Project for Peaceful Competition’ – an international academic network working to foster a constructive global dialogue on great power relationships in an increasingly multipolar world. 

Thomas holds an MA in International Relations and an MLitt in International Security Studies, both from the University of St Andrews.
