The Brexit Effect, 2016–2026

'Ten years on from the divisive referendum, Seldon's timely publication acts as an informed 'conversation' between prominent leavers and remainers, sharing insights and points of view. And that's important. EU-UK relations are still evolving. Brexit may be 'done' but it's certainly not yet dusted.' Katya Adler

'Time to banish any Brexit bafflement. Cause and effect impeccably sourced and superbly dissected in this book for present and future generations.' Nick Ferrari

'An impressively balanced, reflective and thought-provoking collection, which lifts the public debate just when needed. A real achievement.' Tom McTague

'The defining account of Brexit with a remarkable range of key figures from both sides reflecting revealingly and constructively on what happened … and why. A must-read for all of us who want to make sense of it all.' Steve Richards

'With contributions from many of the key players who had a ringside seat for the Brexit referendum, this collection of essays gives a compelling account of the forces that drove the seismic vote to leave the EU and the impact of that decision. It will be essential reading at Westminster as Europe rises up the political agenda again ten years on.' Rachel Sylvester

Sir Anthony Seldon is one of the country's top political historians and acknowledged national authority on all matters to do with the government and No. 10. His book Churchill's Indian Summer: The Conservative Government, 1951–55 (1981) was published forty years ago, and since then he has written or edited many books, including The Blair Effect, 2001–5 (Cambridge, 2005), The Coalition Effect, 2010–2015 (Cambridge, 2015), The Conservative Effect, 2010–2024 (Cambridge, 2024) and The Impossible Office (Cambridge, 2024). He has been the honorary historian at No. 10 Downing Street and chair of the National Archives Trust, and has interviewed virtually all senior figures who have worked in No. 10 in the last fifty years.
