Thatcher's Reforms

How Margaret Thatcher's governments from 1979 privatised industries, curbed union power, fought inflation and deregulated finance, and the lasting debate over the results.

Margaret Thatcher was Prime Minister from 1979 to 1990.

Monetarism: controlling the money supply to reduce inflation.
Privatisation: selling state firms like British Telecom (1984), British Gas (1986), British Airways and later utilities.
Right to Buy: council tenants could buy their homes at discounts.
Union reforms: limits on strikes; the 1984-85 miners’ strike ended in defeat for the union.

The share buyer

In 1984, millions of ordinary Britons bought shares in British Telecom's privatisation, many owning shares for the first time.

Thinking Thatcher's policies had only one effect

They cut inflation and boosted some industries but deepened unemployment and regional decline.
