Task: Question Answering
Input (English): Passage: In 1977, Hayek was critical of the Lib-Lab pact, in which the British Liberal Party agreed to keep the British Labour government in office. 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'. Certainly no liberal can in future vote 'Liberal'". Hayek was criticised by Liberal politicians Gladwyn Jebb and Andrew Phillips, who both claimed that the purpose of the pact was to discourage socialist legislation. Question: The agreement Hayek criticized was between the British Labour government and which political party?
Output (English): British Liberal Party
