The Ridley Plan (also known as the Ridley Report) was a 1977 report on the nationalised industries in the UK. The report was produced in the aftermath of the Heath government being brought down by the 1974 coal strike.
It was drawn up by the right-wing Conservative MP Nicholas Ridley, a founding member of the Selsdon Group of free market Conservatives. In the report he proposed how the next Conservative government could fight, and defeat, a major strike in a nationalised industry.
Ridley suggested contingency planning to defeat any challenge from trade unions:
These recommendations were leaked to The Economist and published on 27 May 1978.
These tactics were successfully employed during the miners' strike of 1984-85, when the National Union of Mineworkers was defeated by the Conservative government of Margaret Thatcher. Thatcher was strongly influenced by other Selsdon Group members besides Ridley, such as Norman Tebbit and Alan Walters. The report had been leaked six years before by The Economist but the unions, especially the NUM, showed no interest in adapting or altering their own tactics in response.
In Ridley's view, trade union power in the UK was interfering with market forces, causing inflation, and therefore had to be checked to restore the "profitability" of the UK. He and others also saw it necessary to check union power in the aftermath of the fall of the Heath government in the face of the 1974 strikes.
