After his dramatic rise to power in the summer of 2019 amid the Brexit deadlock, Boris Johnson presided over the most turbulent period of British history in living memory. Beginning with the controversial prorogation of Parliament in August and the historic landslide election victory later that year, Johnson was barely through the door of No. 10 when Britain was engulfed by a series of crises that will define its place in the world for decades to come. From the agonizing upheaval of Brexit and the devastating Covid-19 pandemic to the nerve-shredding crisis in Afghanistan, the outbreak of war in Ukraine and the Partygate scandal, Johnson's government ultimately unraveled after just three years. This gripping behind-the-scenes work of contemporary history maps Johnson's time in power from start to finish and sheds new light on the most divisive premiership, the shockwaves of which are still felt today.
