I want to know the answer to the following question:
When did Burke become the Prime Minister's private secretary?
All the background I'm provided with is that "In 1765 Burke became private secretary to the liberal Whig statesman, Charles, Marquess of Rockingham, then Prime Minister of Great Britain, who remained Burke's close friend and associate until his untimely death in 1782.". Is that enough to answer the question?
Answer: yes
