The Left Case for Brexit is Richard Tuck’s first book not to be divided into ordinally numbered sections or chapters. Rather, the book is organized chronologically into a series of dated entries, like a diary or daybook. The dated entries trace a trajectory from the run-up to the Brexit referendum in June 2016 to the run-up to the December 2019 UK general election, which offers an absent coda to the present work. Whatever one may think of the political analysis or the political perspective on offer in the work, the book has the pacing of a finely wrought novella. It is engagingly written by an author with a vast array of knowledge, both of the history of political thought and of British history.
