I want to know the answer to the following question:
What was the name of the agreement Hayek criticized in 1977?
All the background I'm provided with is that "Writing to The Times, Hayek said, "May one who has devoted a large part of his life to the study of the history and the principles of liberalism point out that a party that keeps a socialist government in power has lost all title to the name 'Liberal'.". Is that enough to answer the question?
