I've read this twice now, and beyond being a fascinating look into one of the most successful leftist politicians in British history, it's also a fascinating history of British politics generally. It is also, in hindsight, a tragedy; written right before Starmer destroyed all of the progress and momentum built up by the 2017 and 2019 elections, and took power as a far right, violently anti-leftist, pro-austerity, hugely corrupt authoritarian.
The thing that prompted me to reread this was seeing Abbott in person, where she described the current situation as a "low ebb"—a very generous characterisation indeed for the destruction of Labour's internal democracy, the obliteration of it's relationship with unions, the purging of nearly every vaguely leftwing MP and candidate (including a failed attempt at purging Abbott), the most autocratic whip in Labour's history (as I write this, the so-called Socialist Campaign Group has been inactive for almost a year), and the courting of billionaires to make up for a collapse in membership; all to achieve a domestic politics shaped by an austerity so harsh Osborne is salivating and an international politics dominated by active participation in genocide. Low ebb indeed! All respect to Diane, but her choice to remain in it and campaign for it at the last election is an unfortunate stain on her legacy (alleviated somewhat by how angry her presence in the party makes Starmer).
Anyway, that's enough reflection on the current mess. The book is an excellent exploration of a life and career in which there's such an impressive (and unusually consistent) commitment to socialism, social justice, and grassroots politics. Unlike almost every other MP, Diane's remained committed to her principles, refused to be assimilated into a cruel and classist establishment, refused to pull up the ladder behind her. It's frankly startling just how pioneering she's been, how many ceilings she smashed through. Beyond her collection of identity accolades (first black woman MP, first black longest serving black MP, first black person to represent their party at PMQs, etc etc), she also acted as catalyst for countless successful political interventions which shaped future norms: black sections, investigations into education inequality, fights to record ethnicity data (previous "colourblind" reporting hid the scale and violence of structural racism), campaigns for black entrepreneurship, investigations into detention centres, and on and on—and this isn't to include the myriad of principled political interventions which failed, such as anti-war campaigning, attempts to prevent racist immigration bills, and the fight for justice for the victims of Grenfell.
What is clear throughout is the sheer strength and tenacity of Diane as a person. Her fight for justice was tireless in a way almost unique in British politics, and in the face of odds so much greater than almost every MP in history. From being one of only 4 black MPs (and around 5% women MPs), to being reviled and belittled by party leadership, to being suddenly thrust to the forefront by Corbyn's surprise victory and trying to weather the storm of countless betrayals by the Labour rightwing—bouncing around TV interviews with an unmatched energy and eloquence. Her LBC "gaffe" made infamous by a frothing-at-the-mouth media class driven by racism and misogyny, coming when she was singlehandedly managing the media load of an entire front bench (the rest having refused to show as an intentional insult to Corbyn) while also battling with undiagnosed diabetes. And as the book stressed, this was all while singlehandedly receiving almost HALF of all abuse directed to MPs.
In summary, I wholeheartedly the book. As a biography it's excellent, and a political history it's enlightening, and as an anecdote to the vile myths constantly regurgitated about Abbott it's essential. Far too many people on the left aren't aware of the huge debt they owe to her.
