End of the Thatcher era
The Community Charge (Poll Tax)
The policy that ultimately destroyed Margaret Thatcher’s premiership was the Community Charge — universally known as the Poll Tax. Introduced in Scotland in April 1989 and England and Wales in April 1990, it replaced the domestic rates system (which was based on property values) with a flat-rate charge per adult, regardless of income. A wealthy property owner and a low-paid worker in the same neighbourhood paid the same amount.
The policy was widely seen as profoundly unfair. On 31 March 1990, a massive demonstration in Trafalgar Square turned violent — the worst riots in central London since 1886. Cars were overturned, shops looted, and police officers injured. Approximately 339 people were arrested. The television images of burning cars in Trafalgar Square, broadcast around the world, were a severe blow to the government’s authority.
The Poll Tax (Community Charge) was a flat-rate local tax charging every adult the same amount regardless of income. Introduced in Scotland in 1989 and England and Wales in 1990, it provoked the Trafalgar Square riots of 31 March 1990, in which approximately 339 people were arrested — the worst civil disorder in central London since 1886.
Europe and the Cabinet Split
European policy was the other fault-line that cracked the Thatcher government. Thatcher had been a supporter of the European single market (completed in 1992) but was deeply hostile to the idea of economic and monetary union or a federal Europe. In September 1988 she delivered the Bruges Speech, explicitly opposing a European federal state: “We have not successfully rolled back the frontiers of the state in Britain only to see them reimposed at a European level.”
The speech delighted Conservative Eurosceptics but alarmed pro-European colleagues. Tensions came to a head in October 1989 when Chancellor Nigel Lawson resigned after Thatcher refused to allow him to shadow the exchange rate mechanism (ERM) of the European Monetary System. A year later, Deputy Prime Minister and Foreign Secretary Geoffrey Howe resigned in November 1990 over European policy, delivering a devastating resignation speech that compared Thatcher’s treatment of Cabinet colleagues to a cricket captain who “sends in his opening batsmen and then breaks their bats before they go out to the crease.” Howe’s speech directly precipitated the leadership challenge that ended Thatcher’s career.
Geoffrey Howe’s resignation speech in the Commons on 13 November 1990 is considered one of the most devastating in British parliamentary history. Howe, who had supported Thatcher loyally for over a decade, described a Cabinet in which policy disagreements were suppressed rather than debated, where colleagues were undermined in front of foreign dignitaries, and where the Prime Minister’s hostility to Europe was making British foreign policy incoherent. The speech electrified Conservative MPs who had been unsettled by the Poll Tax crisis. Within days, Michael Heseltine had announced his leadership challenge. Howe’s speech is a key example of how personal loyalty, once broken, can accelerate political collapse.
Heseltine’s Challenge and Thatcher’s Fall
Michael Heseltine had resigned from Cabinet in January 1986 over the Westland helicopter affair — a row about whether a British company should be rescued by a European or American consortium, which became a proxy battle over Cabinet government and European alignment. He had since been a visible critic of Thatcher’s leadership style within the parliamentary Conservative Party.
On 14 November 1990, Heseltine announced he would challenge Thatcher for the Conservative leadership. In the first round of voting on 20 November, Thatcher won 204 votes to Heseltine’s 152, with 16 abstentions — four votes short of the outright majority she needed to avoid a second ballot. After consulting Cabinet ministers individually and finding most believed she could not win a second round, Thatcher announced on 22 November 1990 that she would not contest the second ballot and would resign as Prime Minister.
She left Downing Street on 28 November 1990 in tears, recorded by television cameras. John Major won the ensuing leadership contest and became Prime Minister. Heseltine, ironically, did not win — he had brought down Thatcher but not replaced her.

After finding Cabinet colleagues believed she could not win a second round, Thatcher resigned on 22 November 1990. John Major succeeded her.
Thatcher’s fall was strikingly sudden, given that she had won three general elections and dominated British politics for eleven years. Several factors combined. The Poll Tax had made the Conservatives deeply unpopular in the country — polls showed Labour far ahead. Conservative MPs in marginal seats feared they would lose their seats at the next election. The European question had created a group of ministers willing to act against her. Howe’s speech had broken the political convention of loyalty and made dissent respectable. When Thatcher consulted Cabinet ministers individually on 21 November 1990, she found that each one, alone, was willing to tell her she should go — something no collective Cabinet meeting would have produced. Her leadership style — described by critics as domineering and intolerant of disagreement — meant she had accumulated enemies while the circumstances finally aligned to bring them together.
