Tom Fleming is a Lecturer in British and Comparative Politics. He joined the Constitution Unit in September 2021. His research largely focuses on parliament, but he has also written on a number of other topics including cabinet reshuffles and constitutional reform processes. Tom has provided evidence to several recent parliamentary inquiries in the UK.

Before joining UCL, Tom was a Lecturer in the Department of Politics at the University of York between 2020 and 2021. Prior to that, he completed a doctorate in Politics at the University of Oxford.


Tom’s research focuses largely on legislative politics, from both a British and comparative perspective.

His recent work has focused particularly on understanding the way that parliamentary rules are chosen and reformed. As part of this agenda, he jointly runs the ParlRulesData project, which aims to collect and publish data on formal parliamentary rules in the UK and beyond. Tom’s doctorate explored how legislative politics might be changed by voters’ waning attachments to political parties.

Beyond this, Tom has also written on a range of other related topics. In particular, his recent or ongoing projects have explored the government’s power to prorogue parliament, the Johnson government’s proposals for establishing a Constitution, Democracy, and Rights Commission, and the causes and consequences of cabinet reshuffles.


Tom is co-teaching two undergraduate modules in the academic year 2022/23: British Politics and Introduction to Politics. He is also teaching the postgraduate module Parliaments, Political Parties and Policy Making.
