Five years on: How Brexit upended British politics and shocked the establishment

MPs reported unprecedented levels of threats and abuse during the Brexit period; 21 Conservative MPs were expelled from the party for voting against the government.
They'd lost touch with the nation. Whether they ever had touch is another matter.
Lord Hayward reflecting on why the political establishment dismissed his accurate prediction of a Leave victory.

Five years after Britain's June 2016 referendum, the nation pauses to reckon with a democratic rupture that exposed a profound estrangement between governing elites and the working-class communities they believed they understood. What began as a dismissed prediction by a lone analyst became a years-long constitutional crisis — two Prime Ministers fallen, a Supreme Court summoned, MPs threatened and expelled — before an 80-seat election majority in December 2019 finally translated the people's verdict into law. The story of Brexit is, at its core, a story about who gets to define a nation, and what happens when that question is put to everyone at once.

  • A single analyst saw what the entire political establishment refused to: that working-class voters across the industrial North and Midlands were about to upend the order their leaders assumed was settled.
  • The referendum unleashed five years of constitutional chaos — two Prime Ministers destroyed, Parliament deadlocked, the Supreme Court intervened, and MPs subjected to threats and abuse at historically unprecedented levels.
  • Twenty-one Conservative MPs, including Winston Churchill's grandson, were expelled from their own party as Boris Johnson forced the Brexit impasse toward resolution by any means necessary.
  • A nation exhausted by procedural theatre — backstops, flextensions, meaningful votes, and a man shouting outside Parliament for years — finally delivered a decisive mandate in December 2019 that silenced the drama.
  • Britain formally left the European Union on January 31, 2020, only for the true consequences of that departure to be immediately swallowed by a global pandemic, leaving the real work of Brexit still ahead.

On the morning of June 23, 2016, elections analyst Lord Hayward held a prediction almost no one in power wanted to hear: Britain was going to vote Leave. He had spent weeks being dismissed by a metropolitan political class that had lost touch with working-class Labour voters across the industrial North and Midlands. When the results came in, even Nigel Farage appeared to believe he had lost. The establishment's disbelief, Hayward later recalled, was total. "They'd lost touch with the nation," he said simply.

What followed was five years of political convulsion. David Cameron left Downing Street with his children. Theresa May called a snap election that shattered her authority, then watched Parliament reject her Brexit deal repeatedly before departing in tears. The Supreme Court intervened. MPs faced threats and abuse at levels never previously recorded. When Boris Johnson became Prime Minister, he expelled 21 members of his own party — among them Winston Churchill's grandson — for voting against a no-deal Brexit.

Conservative co-chair Amanda Milling remembered the period as a kind of collective exhaustion. The country had spoken once and wanted the drama to end. The political vocabulary of those years accumulated its own strange lexicon — backstops, flextensions, meaningful votes — while a new party called Change UK was born and died, and a man named Steve Bray stood outside Parliament shouting "stop Brexit" until he became part of the furniture.

When Jeremy Corbyn agreed to a December 2019 election, Johnson swept through Labour's traditional heartlands — the very communities Hayward had identified years earlier — winning an 80-seat majority. "There was a giant sigh of relief," Milling said, "not just amongst parliamentarians, but the country as a whole."

At 11 p.m. on January 31, 2020, the United Kingdom left the European Union after 47 years of membership. The ceremony was real, the finality unmistakable. But almost immediately, a global pandemic consumed the political moment, and the actual consequences of Brexit — the reshaping of trade, identity, and Britain's place in the world — were left to unfold in the years ahead. The soap opera had ended. The harder story was only beginning.

Five years before this article was written, on the morning of June 23, 2016, an elections analyst named Lord Hayward made a prediction that would prove far more accurate than anyone in power wanted to admit. Two weeks before the referendum, he told anyone who would listen that Britain was going to vote to leave the European Union. The establishment dismissed him. The polls said otherwise. But Hayward had been watching something the metropolitan political class had missed: working-class Labour voters across the industrial North and Midlands were moving toward Brexit.

Looking back, Hayward described the shock of being right while surrounded by people certain he was wrong. "My biggest memory of the whole process is the sheer disbelief, or misunderstanding, of where the nation was," he told the Standard. He had spent months being corrected by the people in charge, the ones who believed they understood the country. They didn't. "They'd lost touch with the nation," he said. Even Nigel Farage, the Ukip leader who had staked his entire political career on Brexit, appeared to think he had lost when the night began.

What followed was five years of political convulsion that few could have imagined. Two Conservative Prime Ministers fell. David Cameron walked out of Downing Street holding his children's hands. Theresa May called a snap election that destroyed her authority, then spent months fighting her own Cabinet over a deal that Parliament rejected again and again. She left office in tears. The Supreme Court intervened. MPs reported threats and abuse at levels never before seen. The political temperature rose so high that when Boris Johnson became Prime Minister, he expelled 21 members of his own party—including Winston Churchill's grandson—for voting to prevent a no-deal Brexit.

Conservative Party co-chair Amanda Milling remembered the chaos as a kind of national exhaustion. "There was a point where everyone just got so frustrated, they'd had enough," she said. The country had spoken once in the referendum. Now it wanted the drama to end. When Jeremy Corbyn agreed to a snap election in December 2019, the Evening Standard ran a front page headline: "Turkeys vote for Christmas." Johnson won an 80-seat majority, sweeping through Labour's traditional heartlands in the North and Midlands—the very places Hayward had identified five years earlier. The mandate was unmistakable. "I do sense that when we had the exit poll at 10 o'clock, in December 2019 that there was a giant sigh of relief," Milling said, "not just amongst parliamentarians, candidates and the Conservative Party, but also the country as a whole."

The five years had accumulated their own vocabulary: flextensions, backstops, Article 50, meaningful votes. Speaker John Bercow became a household name for his interventions. A man named Steve Bray stood outside Parliament for years shouting "stop Brexit" until he became a fixture of the news cycle. A new political party called Change UK was born and died. Campaigns for a second referendum rose and fell.

On January 31, 2020, at 11 p.m., the United Kingdom left the European Union, ending 47 years of membership. A special Cabinet meeting was held outside London. Clocks counted down in Downing Street. The Union flag flew in Parliament Square. The moment arrived with ceremony and finality. What came next—the true consequences of the decision, the renegotiation of trade relationships, the reshaping of Britain's place in the world—was almost immediately obscured by a global pandemic that would consume the next year and beyond. The referendum had been answered. The political soap opera, as Milling called it, had reached its climax. But the actual work of Brexit was only beginning.

My biggest memory of the whole process is the sheer disbelief, or misunderstanding, of where the nation was.

There was a point where everyone just got so frustrated, they'd had enough. The country was saying: we've spoken once, we spoke in the referendum, now just get on with it.

Lord Hayward saw something everyone else missed. What was he actually looking at that the polls and the establishment couldn't see?

Model

He was listening to people the political class had stopped listening to. Working-class voters in the North and Midlands weren't being captured by traditional polling because they'd already checked out of the conversation the establishment was having. They were ready to vote against the system itself.

Inventor

But why did it take five years to actually leave? The referendum was clear.

Model

Because Parliament didn't want to accept the result. MPs kept voting down deals, the courts got involved, Prime Ministers fell trying to find a compromise that didn't exist. The country had to vote again—not on Brexit, but on whether to finally implement the first vote.

Inventor

Amanda Milling called it a "political soap opera." Does that capture what actually happened?

Model

It does, but it misses something. A soap opera is entertainment. This was real people's lives and futures being debated in Parliament while MPs received threats like never before. The drama was real, and it was exhausting.

Inventor

Johnson's 80-seat majority came from the same places that voted Leave in 2016. Was that inevitable?

Model

Not inevitable, but it was waiting to happen. Those voters had spoken once and felt ignored. When they got a chance to speak again, they voted for the person who said he'd actually do what they asked. That's not a soap opera—that's accountability.

Inventor

What got lost in all of this?

Model

The actual conversation about what Britain should be. Instead we got five years of procedural fighting. By the time we left, nobody was even talking about the vision anymore—just about ending the chaos.
