Divisive, controversial, atypical - few others embody the fraught nature of British politics today quite like John Bercow. A man who is revered by his one-time political opponents and chastised by his former bedfellows. A politician who has traversed the deep chasm between the Conservative right and the liberal left. A Speaker some see as a great moderniser and others, a constitutional arsonist.
With Brexit left unresolved, Bercow is determined to ensure that he, the 157th person to occupy the Speaker's Chair, has left an indelible imprint on the history books.
From suffering at the hands of bullies to standing up for backbenchers in the Commons, this is the story of John Simon Bercow, the son of a taxi driver from North London, and one of the most fascinating characters to grace the corridors of the Palace of Westminster.
