I want to know the answer to the following question:
What position did the British Prime Minister's secretary of state previously hold?
All the background I'm provided with is that "After winning the United Kingdom general election, 1979, Margaret Thatcher appointed Keith Joseph, the director of the Hayekian Centre for Policy Studies, as her secretary of state for industry in an effort to redirect parliament's economic strategies.". Is that enough to answer the question?
Answer: yes
