The establishment had assumed its warnings would be heeded. Instead, people were rejecting it.
Ten years after Britain's most consequential democratic vote, an oral history of the 2016 Brexit referendum illuminates how a five-month campaign exposed the deep fractures between governing elites and the governed. From Boris Johnson's anguished defection to the Leave cause, to the murder of MP Jo Cox by a white supremacist, to David Cameron's resignation on the morning after, the referendum became a mirror held up to a society that had quietly stopped trusting its institutions. The story of Brexit is, in the end, a story about what happens when the language of expertise and the language of belonging no longer speak to each other.
- Boris Johnson's surprise endorsement of Leave—made after a weekend of genuine anguish and political calculation—instantly transformed a manageable referendum into an existential crisis for the British establishment.
- The Remain campaign's failure to reach working-class voters was not merely strategic incompetence but a symptom of a deeper disconnection: its warnings about roaming charges abroad meant nothing to communities living with real economic precarity.
- The Leave campaign's red bus lie about £350 million a week was never meant to survive fact-checking—it was designed to dominate the emotional landscape, and it did, turning debunking itself into free advertising.
- Jo Cox's murder by a far-right extremist one week before the vote fused with Nigel Farage's 'Breaking Point' immigration poster in the public mind, revealing how thoroughly violent rhetoric had saturated the campaign's atmosphere.
- When Sunderland—a city whose Nissan factory owed its existence to EU membership—voted decisively to Leave, it confirmed that the referendum was never really about economics: it was a verdict on who gets to be heard.
- Cameron's resignation the morning after, and Johnson's stunned expression in victory, suggested that both men had gambled on an outcome they never truly believed would arrive—leaving a country in uncharted waters with no one at the helm.
In February 2016, David Cameron set June 23rd as the date for Britain's referendum on EU membership, confident the question could be settled once and for all. Within days, Boris Johnson—whose support Cameron had taken for granted—announced he was joining the Leave campaign after a weekend of genuine torment at his Oxfordshire farmhouse, torn between calls from the prime minister, the chancellor, and his own family. The announcement, made to waiting press after an hour of prevarication, would later be described as the moment that changed the course of history.
The campaign that followed exposed a country divided not just on Europe but on trust itself. The Remain side was disorganized and remote, its messaging calibrated for people who holidayed in Málaga rather than those facing real economic anxiety. Leave, by contrast, was disciplined and ruthless. A red bus carrying the claim that Britain sent the EU £350 million a week toured the country; when journalists challenged the figure, Leave strategists were unmoved—even a corrected number was still a large number, and voters were doing the arithmetic in their heads.
In mid-June, the two campaigns collided on the Thames in a moment of pure spectacle. Nigel Farage led a flotilla of fishing boats toward parliament; Bob Geldof arrived with Remain supporters to counter them. The chaos that followed—shouting, V-signs, media helicopters—looked, to those watching at home, like metropolitan elites mocking working men. Farage understood the optics immediately. What few knew at the time was that Jo Cox's husband and children were on a tender nearby, watching it all.
The following day, Farage released a poster showing Syrian refugees at a border crossing under the words 'Breaking Point.' Hours later, Cox—a 41-year-old Labour MP and vocal Remain campaigner—was shot and stabbed to death outside her constituency office by a man shouting 'Britain first.' The murder and the poster became inseparable in the public mind. Her Westminster colleagues grieved together, newly aware that their work carried physical risk. Jess Phillips, who had seen Cox just 48 hours earlier and told her she loved her, rang her number from Spain after hearing the news, leaving messages asking her to call back when she was feeling better.
The campaign resumed, and many assumed the tragedy would shift the outcome. It did not. On the night of June 23rd, Sunderland—home to a Nissan factory built on EU membership—voted Leave, and its workers cheered. At the Remain party in the Festival Hall, the temperature seemed to drop. By morning, Britain had voted to leave the European Union. Cameron resigned within hours, walking out of Downing Street with his wife beside him. Johnson, who had won, looked stunned—as though he had never quite believed it would happen, and now had no idea what to do next.
In February 2016, David Cameron set a date for Britain's reckoning with the European Union: June 23rd. The prime minister had promised a referendum years earlier, a gamble he believed would settle the question once and for all. Within days, Boris Johnson—then London's mayor, a man Cameron had assumed would back remain—announced he was joining the leave campaign. The decision shocked the prime minister's inner circle, though some saw it less as principle than as ambition. Johnson spent that weekend at his Oxfordshire farmhouse, genuinely torn, buffeted by calls from Cameron, George Osborne, and family members. His communications director found him so conflicted that when asked what to do, Johnson could only prevaricate for another hour before stepping outside to announce his choice to the waiting press. That announcement, as one observer would later say, changed the course of history.
What followed was a campaign unlike any Britain had seen. The remain side, led by Cameron and his team, was disorganized and tone-deaf. Labour MP Jess Phillips knocked on doors in her constituency only to find there was no campaign infrastructure to support her. The messaging felt remote—warnings about lost mobile roaming in Málaga meant nothing to voters facing real economic anxiety. Meanwhile, the leave campaign was disciplined and ruthless. A red bus toured the country with a claim that Britain sent the EU £350 million a week, a figure widely debunked but impossible to escape. When journalists pressed the figure, leave strategists smiled: even if the real number was half that, voters at home were thinking about how much money it was. The lie became the story, and the story became the campaign.
On the Thames in mid-June, the two sides collided in a moment of pure theater. Nigel Farage and Kate Hoey led a flotilla of fishing boats upriver to parliament, a show of ordinary working people demanding their voice be heard. Bob Geldof arrived with remain supporters to counter them, and the spectacle descended into chaos—V-signs, shouting, media helicopters overhead. Rachel Johnson, Boris's sister and a remain campaigner, later realized the optics were catastrophic: it looked like metropolitan elites mocking working men. Farage spun it brilliantly. The image of establishment figures sneering at fishermen would haunt the remain campaign for days. What Johnson's sister didn't know at the time was that Jo Cox's husband and children were on a tender nearby, watching it all unfold.
The next day, Nigel Farage released a poster showing Syrian refugees at a border crossing, with the words "Breaking Point: the EU has failed us all." It was a raw appeal to fear, and it exploded across the media. Hours later, Jo Cox—a 41-year-old Labour MP who had been a vocal remain campaigner—was shot, stabbed, and kicked to death outside her constituency office by a man shouting "Britain first." The murder and the poster became fused in the public mind, a symbol of how toxic the campaign had become. Craig Oliver, Cameron's communications director, would later describe it as the moment he realized something had deeply gone wrong in the country. The establishment had assumed its warnings would be heeded. Instead, the British people were telling the establishment they didn't believe it, didn't trust it, and didn't want to be told what to do.
Cox's death silenced the campaign for days. Her colleagues in Westminster—Jess Phillips, Tom Watson, others from the 2015 intake—grieved together, feeling hunted, understanding that their jobs now carried real risk. Phillips had seen Cox just 48 hours before her death, at a party celebrating their cohort. She had told Cox it would be all right. She had said she loved her. When the news came through while Phillips was in Spain, she rang Cox's number anyway, unable to believe it was real, and left messages saying everything would be okay, call her when you're feeling better. The campaign resumed, but something had shifted. The question now was whether the murder would change minds. Many assumed it would. They were wrong.
On June 23rd, the results came in slowly, then all at once. Sunderland voted to leave—Sunderland, where the Nissan factory sat, where workers had benefited from EU membership. The workers cheered. At the remain party in the Festival Hall, the temperature seemed to drop. Robert Peston, the ITV political editor who had spent months warning that Brexit would make Britain poorer, watched the economics he had cited prove irrelevant. People were voting for something else: control, identity, a rejection of the people telling them what was good for them. By morning, it was over. Britain had voted to leave. David Cameron, who had called the referendum to settle the question, resigned within hours. He walked out of Downing Street with his wife Sam beside him, and the country moved into unknown territory. Boris Johnson, who had won, looked shocked—as if he had never quite believed it would happen, and now had no idea what came next.
Notable Quotes
That announcement changed the course of history.— Boris Johnson's communications director, on Johnson's decision to back leave
The establishment had assumed its warnings would be heeded. Instead, the British people were telling the establishment they didn't believe it.— Craig Oliver, Cameron's communications director

The Hearth Conversation Another angle on the story
Why did the remain campaign fail so badly when it had the entire machinery of government behind it?
Because machinery isn't the same as connection. They had resources but no real understanding of what people actually feared or wanted. They talked about economics and trade deals while leave was speaking about control and identity. It was a mismatch of languages.
And Boris Johnson—was he genuinely undecided, or was it always about positioning himself for the future?
His own people say he was genuinely torn. He was pro-European, but he had problems with the EU. The political calculation was probably there too, but the division seemed real. What's interesting is that even after he won, he looked crestfallen. Like he'd won something he didn't fully understand.
The £350 million bus—everyone knew it was false. Why did it work anyway?
Because leave understood something about modern campaigning: the lie doesn't have to survive scrutiny. It just has to dominate the conversation. Every time journalists debunked it, they were repeating the number. The message was in the repetition, not the truth.
Jo Cox's murder happened just a week before the vote. How did that not change everything?
People thought it would. Her colleagues certainly thought it would. But by then the campaign had already tapped into something deeper—a feeling that the establishment was out of touch, that experts couldn't be trusted. A tragedy, even a shocking one, couldn't compete with that.
What did Cameron's resignation the morning after signal?
That the old order was ending. He had tried to manage the party, to settle the question, to use his authority to persuade. He lost on all counts. When he walked out, it was clear that the people telling you what was good for you no longer had that power.
