At Bruges, she made a speech in which she outlined her opposition to proposals from the European Communities for a federal structure and increasing centralization of decision-making believing that the role of the EC should be limited to ensuring free trade and effective competition. She was specifically against Economic and Monetary Union, through which a single currency would replace national currencies, and for which the EC was making preparations. In 1989 the economy high interest rates were imposed to stop an unsustainable boom. At the Madrid European summit, Nigel Lawson and Geoffrey Howe forced Thatcher to agree the circumstances in which she would join the Exchange Rate Mechanism, a preparation for monetary union. She took revenge on both by demoting Howe and listening more to her adviser Sir Alan Walters on economic matters. Lawson resigned that October and in November, a so-called ‘stalking horse candidate Sir Anthony Meyer challenged Thatcher for the leadership of the Conservative Party. In 1989 a new system of local government finance to replace the rates was introduced for Scotland in 1989 and for England and Wales in 1990. Called the 'Community Charge' but known as the Poll Tax was applied at the same amount to every individual resident with only limited discounts. Widespread opposition culminated in a huge [http://newsfilm.bufvc.ac.uk/article.php?story=200510081953085 demonstration] in London on March 31 that turned into the largest outbreak of public disorder central London had seen in a century which was followed by millions of people refusing to pay the tax. This along with her government's handling of the economy, her perceived arrogance and a general feeling that she would never retire,  made her politically vulnerable. Geoffrey Howe resigned on November 1 and condemned Thatcher's policy on the European Communities then openly invited 'others to consider their own response'. Michael Heseltine's response was a leadership challenge which resulted in a narrow failure, by two votes, for Thatcher to win automatic re-election. After consulting with cabinet colleagues she found a vast majority thought that she could not win on the second ballot. On November 22nd Thatcher announced that she would not be a candidate in the second ballot. She supported John Major as her successor, and retired from Parliament at the 1992 election.

Lawson resigned that October and in November, a so-called ‘stalking horse candidate Sir Anthony Meyer challenged Thatcher for the leadership of the Conservative Party. Meyer never had any realistic chance of winning, but many saw his challenge as evidence of Thatcher's declining support within the party.

Michael Heseltine's response was a leadership challenge which resulted in a narrow failure, by two votes, for Thatcher to win automatic re-election. While this was initially blamed on the shockingly inept campaign run on Thatcher's behalf by her close ally, Peter Morrison, after consulting with cabinet colleagues she found a vast majority thought that Heseltine's performance in the first round would embolden the Anti-Thatcherites within the party, and that she would probably not win on the second ballot. On November 22nd Thatcher announced that she would not be a candidate in the second ballot. She supported John Major as her successor, and retired from Parliament at the 1992 election.
