Boris Johnson. The Gambler (Bower Tom); Penguin, 2022

As divisive as he is beguiling, as misunderstood as he is scrutinised, Boris Johnson is a singular figure.

Many of us think we know his story well. His ruthless ambition was evident from his insistence, as a three-year-old, that he would one day be 'world king'. Eton and Oxford prepared him well for a frantic career straddling the dog-eat-dog worlds of journalism and politics. His transformation from bumbling stooge on Have I Got New for You to a triumphant Mayor of London was overshadowed only by his colourful personal life, brimming with affairs, scandals and transgressions. His ascent to Number 10 in the wake of the acrimonious, era-defining Brexit referendum would prove to be only the first act in an epic drama that saw him play both hero and villain - from proroguing parliament to his controversial leadership of the Covid-19 Crisis, all against the backdrop of divorce, marriage, the birth of his sixth child, revolts among Tory MPs and the countdown to Brexit.

Yet despite his celebrity, decades of media scrutiny, the endless vitriol of his critics and the enduring adoration of his supporters, there is so much we've never understood about Boris - until now. Previous biographies have either dismissed him as a lazy, deceitful opportunist or been transfixed by his charm, wit and drive. Both approaches fall short, and so many questions about Boris remain unanswered.

What seismic events of his childhood have evaded scrutiny? How has he so consistently defied the odds, proved his critics wrong, and got away with increasingly reckless gambles? What were his real achievements and failures as Mayor of London, what was really going on during his time as Foreign Secretary, and why did he write two articles for the Telegraph, one in favour of Leave and the other for Remain? How have the women in his life exerted more influence than any of us realise, and why is his story ultimately one overshadowed by family secrets?

Based on a wealth of new interviews and research, this is the deepest, most rounded and most comprehensive portrait to date of the man, the mind, the politics, the affairs, the family - of a loner, a lover, a leader.

Revelatory, unsettling and compulsively readable, it is the most timely and indispensable book yet from Britain's leading investigative biographer.
