Liz Truss's disastrous premiership was the shortest and most chaotic in British history. In the space of just 49 days, Truss witnessed the death of the longest-reigning monarch, attempted to remould the economy, triggered a collapse in the value of Sterling and was forced on a series of embarrassing U-turns that ultimately led to her resignation. The aftershocks of her time in office are still felt today. How did she blow her opportunity so spectacularly?

Based on exclusive interviews with key aides, allies and insiders, and focusing on the critical steps that led to her demise, this gripping behind-the-scenes work of contemporary history gives the definitive account of Truss's premiership.
